Hey guys,
I am looking for a usb-c pd compatible battery pack with a small form factor. capacity is not my main concern, but the form factor and a fast charging speed is. However, I can find none.
I can find lots of quick charge 2/3 battery packs, but are these safe to use? Thanks for your help
I think its OK with non-PD charger.
It won't enable rapid charging if you are not using PD charger and will only give you normal 5V2A.
Unfortunately USB-PD chargers seem to be in their infancy where most USB-PD chargers seem to have faults and some may even kill your pixel.
Belson/Nathan K have made a list of cables and chargers they have tested for the Pixel here https://docs.google.com/spreadsheet...x9dMDWqENiY2kgBJUu29f_TX8/edit#gid=1288176877
If I was you I would go for a non PD 5V 3A charger as it will charge at 15W which is only 3W of what you could get with PD Charging and often you would end up with less anyway.
Just keep using your existing battery pack with a USB-A to C cable with 56 ohm resistor (like the oem cable)

Hey all,
Has anyone used the Apple Macbook's 29W charger with their Pixel C? - Any thoughts? did it charge at a higher rate over the standard 15W?
On the same note, anyone tried with the Chromebook Pixel's 60W charger?
I notice Google sells a universal type-C 60W charger but it says the maximum current is 3A, either at 5V, 12V or 20V. I suspect this means it's not going to charge the Pixel any faster since it probably just takes the 5V output.
I would be very cautious of any Type C chargers and cables. I have learned a lot from reading the reviews and google posts from Benson Leung. He keeps a list of devices and cables that he has tested.

Anyone use a Targus APA93US APA93 45W Type-C Charger? (Currently on sale at Best Buy for $30. Same on Amazon for prime members)
EDIT: I asked Benson Leung, he worked with the Google Pixel C team and says the charger is PD, although before PD rules were set. So it is missing 9V. But assures me that the Pixel C can also make use of it's capabilities using the 12V/2A to get max fast charge of 24W which is what the Pixel C can use.
Does anyone else have the Motorola TurboPower 30? It is compatible with the MACbook using 5V/5A, wonder if the Pixel C can negotiate, it seems to have a proprietary Power Delivery.
UPDATE: I've tested it. It can only negotiate 5V/3A 15W~ max.

According to Benson Leung, which worked on the Pixel C at google, it can do 9V/2.67A or alternatively use 12V/2A. Which ever the usb type-c PD charger is capable of. The Pixel C can make use of up to 24W max for fast charging with compatible Power Delivery Chargers.

UPDATE: I've used the Targus APA93US 45W USB Type-C wall charger and it can negotiate 12V/2A 24.5W~ providing 33% more charging speed. Great for $30 at best buy or prime.
I recently bought this OEM Verizon / Xentris charger XENTVLPD-XX1 / TYPECPDQC3TVL on eBay for $8~ YMMV http://www.ebay.com/itm/351967678957
It can handle 5v/3a 7v/3a 8v/3a 9v/2.7a 12v/2a which is ideal for "faster" charging the Pixel C at 24W max, 33% over stock/OEM charger.
Received both my OEM and Original Verizon / Xentris chargers
XENTVLPD-XX1 / TYPEC27PDQC3TVL today and went to town doing some simple testing with various cables. With screen on it charges at about 15-16W with the screen off it ramps up to 24-25W. It's compact and very sturdy.
My conclusion is, if you're looking for a USB Type-C charger capable of Power Delivery, look no further. This is excellent and for the price $8~ shipped is an incredible deal. I bought mine from this listing on eBay http://www.ebay.com/itm/351967678957
There is a lot of ongoing work by companies to manufacture charging products for new USB Power Delivery (USB-PD) and Qualcomm Quick Charge (QC) devices. Because the USB-PD and QC specifications are at direct odds with each other, the products are difficult to standardize, leading to confusion among consumers. Essentially, anything that does not adhere to the strict USB-C specifications is considered in violation. Google Engineer Benson Leung has tested numerous USB-C cables and chargers and found many to not be within USB-C specification. This implies they may be dangerous for USB-PD devices. However, I have not seen any true proof of QC chargers damaging USB-PD devices, only that they will not fast charge them.
The engineering points are numerous and can get fairly complex, beyond the scope of this review. However, I find it important to add to the fount of knowledge with our new phones and charging devices, and this is my small contribution.
I own a LG G5 phone, and my testing and comments are limited to this device only.
My simple method is to use a USB-A multimeter as well as the Android OS’s amperage reading. There are limitations to this. Primarily, I have been informed that the Android OS amperage is based on a voltage of 5V. This was certainly fine in the days pre-Qualcomm Quick Charge, but now with higher and variable voltage, the amperage readings are not reliable. Secondly, as this is a USB-A meter, I have no way of directly monitoring USB-C amperage or voltage. Thirdly, I do not have the ability to digitally log the voltage off the multimeter, so some of the data points presented are more general than I would like.
Here I am reviewing the Tronsmart Presto 12000mAh battery pack, which has both a USB-C port for USB-PD devices (Nexus 6P, etc) and a USB-A port for QC3.0 devices (LG G5, HTC10). It is available here:
https://amazon.com/gp/product/B01GVBFBBO/ref=ox_sc_sfl_title_4?ie=UTF8&psc=1&smid=ALTVS0Q5KJ7M3
It was provide to me for my review.
The main selling point of this battery pack aside from the QC3.0 capability is the dual types of ports. If you happen to have both QC3.0 and USB-PD devices, this battery pack can theoretically fast charge either. The QC3.0 port is rated at the usual QC3.0 voltages/amperages, and the USB-PD port is rated at 5V/3A. It comes with a short USB-A to USB-C cable to be used with the QC3.0 port. You’ll have to supply your own double-ended USB-C cable if you want to go C to C.
There’s a 4 LED gauge for how much battery is left. During charging, the LED at the end will flash. On the side there’s a button to turn on the charging. The battery is charged through the USB-C port (it’s used both for output and input). Attached to my separate QC3.0 AC adapter, the battery charged at 2.4A / 5V only. I do not have a USB-PD charger to use to charge the Presto.
EDIT: I re-tried the charging measurements using a Tronsmart branded QC3.0 AC adapter and the battery now charged at 15W, ~2.7A and 5.6V. This is better than the prior measurements! Your charging adapter matters!
For this test, I used the included USB-A to USB-C cable for the QC3.0 port. My USB-C to C cable is one provided by ChoeTech (available here https://amazon.com/gp/product/B01H3COF62/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)
I drained my phone down to ~20% and plugged in. Here is how the charging times for the Presto battery ports compare:
To go from ~20 to 100% for QC3.0, it took ~70 minutes. For the USB-PD port, it took 90 minutes. The mA readings for the QC3.0 are not accurate, but those reported by the Android OS. The USB-PD amperages are likely correct.
I have previously tested several QC3.0 and QC2.0 chargers. The charging time for the QC3.0 port lines up well with my multiple previous measurements. Those show that for 0-100%, it takes ~80 minutes, with ~20% increase/10 minutes for the first 20 minutes.
For the QC3.0 port, here are some general points collected from me taking notes on the multimeter readings:
Wattage maxed out at ~16-17W. Not bad!
Voltage maxed at 8.70 very briefly. Most of the early measurements (fastest charging) were at 6.4-7.4 volts.
Amperage maxed at ~2.6 briefly.
These measurements all fall within QC3.0 guidelines.
Regarding the USB-C port readings, it seems that despite a recent Gtrusted.com review,
http://gtrusted.com/review/lg-g5-su...-to-qualcomm-quick-charge-3-0-over-usb-type-c
which reported the LG G5 is also capable of negotiating charging over the USB-PD standard, many kinks and incompatibilities remain. Gtrusted.com subsequently found that the G5 cannot charge at all from the Anker or iVoler USB-PD charger USB-C ports:
http://gtrusted.com/review/40938
http://gtrusted.com/review/40937
I did not have that issue with the Presto, but the USB-PD port charging times were suboptimal. They lagged behind QC3.0, and an additional 15-20 minutes was necessary to top off the phone. I doubt the G5 is able to extract the 5V @ 3A the port is advertised to provide for USB-PD devices and that the initial Gtrusted report suggested.
Previous to my testing, I had wondered if the G5 would get the fast charging benefits of USB-PD chargers. In this case, it does not. As I mentioned in the introduction, the standards of USB-PD and QC clash with each other. Specifically, it is very unclear how manufacturers are implementing charging through USB-C ports.
Some earlier models had put QC3.0 into USB-C ports, which is in violation of USB-PD standards. BUT, I want to point out, why and how does that even affect QC capable devices? It really doesn't. The outrage on retailers such as Amazon is driven by the USB-PD side, neglecting entirely Qualcomm’s tested standard. Manufacturers in turn are removing their QC implementation from the USB-C ports and leaving them USB-PD only.
One notable issue I discovered was with the phone after the charging finished on the USB-C port and the battery auto-shutoff. The phone made repeated connecting/disconnecting sounds despite the battery pack being off. I think this is solely a G5’s issue though--perhaps the G5 detects a USB-C device but cannot successfully interface with it. The same thing occurs when the battery pack is off and you first plug in the USB-C cable. This subsides once the battery pack is turned on.
In conclusion, having 2 fast charging solutions in one battery pack is a worthwhile luxury. It’s great to see products like this fill the need. Having full-fledged QC3.0 capabilities in a portable unit makes travel and juicing up quick, easy and convenient.
Pros:
2 different ports to charge either USB-PD or QC3.0 standards! There are few options like this these days.
QC3.0 amperage, voltages, and charging times are similar to AC QC3.0 adapters!
Auto-shutoff is a nice feature to preserve battery life.
Includes a USB-C compliant USB-A to USB-C cable, a necessary touch to charge the battery if you don't already have one
If you have a capable QC3.0 charger, the battery will charge at ~15W
Cons:
The G5 does not charge at 3A/5V with the USB-C port. My estimates suggest it is more like 5V @ 2A. This may not be any fault of the charger but rather the programming controlling the charging from the phone.
Other:
The USB-C port interface with the G5 results in repeated connects/disconnects if the battery is not off. This is more likely an issue with the phone than the Presto.
2 different ports means 2 different cables to carry!
The outrage on retailers such as Amazon is driven by the USB-PD side, neglecting entirely Qualcomm’s tested standard. Manufacturers in turn are removing their QC implementation from the USB-C ports and leaving them USB-PD only.

This is not a good power bank to have if one does not already own a device that accepts USB-PD. Reason is this powerbank will only accept 5V3A input to charge itself. The A port cannot be used to charge it. So you cannot QC this powerbank.
So unless you have a charger with a c port that you can connect with a c to c cable, you will only be able to input 7-8W to charge this bank up instead of twice as much. The bank will take twice as long to charge.
That is not true. It *can* take either USB-PD C input or QC input to charge, and it is not only 7-8W, but rather 15W with the QC3 charger. I was afraid of that also, as USB-PD accessories are not so common yet, but my testing (and also from that other review) indicate otherwise.
I had an earlier version of this review using a different brand QC charger, and what you said was the case. Quite slow, 10W charging only (5v @ 2A). But with the Tronsmart QC3 charger, this is not the case.
The 7 Pro is supposed to support 5v/3A, 15W charging from a Power Delivery charger, but I'm only seeing 4.5v/1.8A, which is about 8W slow charging.
Am I reading this wrong? What's the best/highest/fastest charging you've seen from a PD charger?

Your battery is above 50% and charging speed slows with increasing battery percentage. To determine maximum speed of USB PD for the OP7Pro you need to check at a lower charge level. Warp charge will also not charge with 30W all the way.
What battery app is that?
Even with the OP charger once you get to 50-70% changing rate slows down by at least 50%, try when the phone is at 10% and then watch it for a couple minutes, that will tell you the max for that particular charger

It's the built in diagnostics. Dial *#808# in the OP Phone app.
Swipe to the second screen, "Device debugging", and there's one test for Normal Charger, and one for Fast Charger.

That's a great point, thanks! I'll try again from a lower charge state!
OnePlus has said it supports 15w PD while screen is off and 5v 1.5a while display is on.

I'm seeing the same thing. I tried three different USB PD chargers that I used on my Pixel XL. The highest charge current I saw was 1980mA. The battery was in the low to mid 30% range. I used the Ampere app. To check the accuracy of the app, I tried two things. 1. I used the stock Oneplus Warp charger and Ampere showed 5740mA (wow, 5.7A is kicking some butt!). 2. While using my Belkin USB-PD car charger, I noted the voltage and current coming from my bench power supply. The bench supply was outputting about 10W so an Ampere reading of about 8W of energy into the phone made sense. I used three different cables too.
All my cables are USB-C to USB-C since all my PD chargers have a USB-C port on them. I see the standard for USB 3.1 has a max rating of [email protected] which can be done over a USB-A to USB-C cable. I wonder if the only way to get 15W into the phone (besides the Oneplus chargers) is to use a USB-A to USB-C cable with a charger that has a USB-A port and can support 3A? Edit: No, more research shows there there should be no problems with C-C. The Belkin PD car charger I have doesn't specifically say it supports [email protected], but the Anker AC USB charger does list [email protected] I can't get more than about 1900mA out of it even with the battery low.
I basically support all the users that OP failed this point to include proper USB PD function. Only 7.5w to 10w is supported without any dash or warp charger. Confirmed
should be fixed with 10.0.2
Power Delivery (PD) is very complex. For example the USB PD Revision 3 specification is 657 pages. Much of the complexity involves the negotiation protocols between chargers and phones or other devices. In cases where a compatible protocol can't be negotiated between a charger and phone the page 242 of the spec says: "Shall supply the default [USB 2.0], [USB 3.2], [USB Type-C 2.0] (USB Type-C®) or [USBBC 1.2] voltage and current to VBUS when a Contract does not exist (USB Default Operation)." That's my guess why people are seeing lower charging currents than advertised by the chargers.
The OP's charger has this interesting cryptic note on their Amazon page: "Rapid charge: USB-C charger delivers 45-watts of power to charge and recharge all of your important devices at a high speed with PD 3. 0 (5V/ 3a, 9V/ 3a, 12V/ 3a, 15V/ 3a, 20V/ 2. 25a) Note: USB adapter will not be able to trigger the PD protocol

Hello
So a couple of weeks back I upgraded to the Poco F2 Pro 6/128GB from my Mi 9T.
I have been using a magnetic charging cable with my Mi 9T, with a little magnetic part permanently in the usb port for convenience with a standard QC3.0 charger. Worked great and charged fast at 18W.
I wanted a similar solution for my Poco F2 Pro.
So I have done some testing and the results might surprise you.
Poco supports 30W Mi Turbo Charge which seems to be a custom Xiaomi charging protocol and does not seem to play nice with standard USB PD3.0 Protocol.
I have done charging tests from ~5-20% battery for maximum charging speeds and tested the actual charge rates with a USB Voltmeter
Voltmeter:
https://www.ebay.co.uk/itm/USB-Mete...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Test 1: Original Charger and Cable
Result: 30W Mi Rapid Charging (~9.6V, 3.1A) As Expected
Even tho the original charger is rated at Max 33W, Poco only charges at 30W Max.
Test 2: 60W USB PD3.0 Charger + 5A Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B07QPNRGYH/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
I did multiple tests to check if the charger is legit (which it is, many of my friends use it with different devices and it works great) with my brothers Pixel 4XL, and my friend Xiaomi Mi 9.
Pixel Charged at 18W, Mi 9 at 27W.
The phone did not charge at 27W (~9V 3A), even to it does support PD 3.0 charging.
Test 3: Original Charger with a 3A Ugreen Magnetic Cable
Cable: https://www.ebay.co.uk/itm/Ugreen-M...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
This is very interesting since it does trigger the Mi Turbo Charge, it is not the full speed charge like with the original setup.
Original setup also has a charging animation, with the % increasing at a steady speed.
With the Ugreen Cable, there was no animation.
Test 4: Original Charger + 40W Huawei Supercharge Cable
Cable: https://www.amazon.co.uk/gp/product/B08CR7W2T1/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
The original Xiaomi Cable is a 5A Cable, so I thought id try a Huawei Supercharge Cable, but it ended up charging the same as a 3A Ugreen Cable
Test 5: 60W USB PD3.0 Charger + 5A Magnetic Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B08HLN27DP/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
Again, standard 18W fast charging, not 27W as you would expect.
Conclusion:
From my testing, the only way to charge the Poco at Maximum speed of 30W is with the charger and cable which I find very strange. Does the original Xiaomi cable have a custom Xiaomi chip which handshakes with the charger to get the full 30W Mi Turbo charge?
With a PD3.0 Charger, I was only able to achieve 18W of fast charging, again very strange, since Poco should support 27W (~9V 3A) charging with any PD3.0 Charger.
I have settled for a setup with the Ugreen Magnetic Cable and the Original Charger for convenience, ease of use and preventing the USB port from being worn out. I am loosing about 5W of speed, which does slightly increase the charging time. (I charge my phone to ~85% max)
(If there is something wrong with my methodology let me know and I will re-test if needed)
I approved with an Aukey 29w Fast Charging charger (model pa-y7) and the same charge at 18W, even with the type-c cable on both sides (Baseus brand cable up to 60W)
It seems like Xiaomi cable and charger have an extra pin. That might trigger and power the turbocharge

I don't know at which rate it charges but it triggers Charge turbo animation with the % increasing at a steady speed with almost any proper USB-C to USB-C cable.
I've also found that if you launch the CIT on the phone by tapping on kernel version 3 times on settings->About this phone->All specs
and go to the charging test (number 24) you can check which protocol is being used
If you use any QC3.0 charger it says USB_HVDCP, which triggers fast charging but not the charge turbo animation.
If you use a regular PD charger it says USB_PD which also triggers fast chargingbut also not the charge turbo animation.
If you use the original setup it also says USB_PD which means that extra pin it has on the USB-A connector is wired in a weird way it actually negotiates usb PD protocol, which I can also confirm because I connected it to a Thinkpad T480 and with the Lenovo Vantage software gets 27W charging, which is not possible with any USB-A to USB-C cable and QC3.0 charger.
Which may mean that maybe Xiaomi didn't want to pay for the QC4.0+ chipsets or something and did some weird stuff to get PD through QC3.0 by that pin and through the F2s software reducing the cost of the charger in the box and whatever else. As for this GaN 65W charger I have no idea on how they pull that off but is a proper PD charger
Since the update to Android 11, a set of cables that previously triggered the Turbo Charge, now suddenly work only as Fast Charge.
They were a bit slower than original before, but now they are a lot slower.
I only have the Accubattery measurements:
cca 4000 mA average on Android 10,
cca 3000 mA average on Android 11.
While the original charger + cable shows about 4500-5000 mA average.
They really managed to screw this device.
On ArrowOS my device charging at 1.8A and 7.5V with original charger and wire... so it depends on software. But anyway I don't want to downgrade from perfect OS to buggy MIUI only because of that.
I also have seen a weird change in charge speeds..
Used to be totally fine but it seems that for a while now the speeds are very slow and quickcharge isnt working anymore..

hey have the same problema. here. teh only way to get fast chager is with the original charger al cable. PD charger give me fast charge. but all my other chargers that gives me fast charger in other devices gives me NOTHING now.
original charger 4300 ma,
PD: 1200 ma
fast chargers QC 3 and others: 230 ma !!
****ty old chargers : 230 ma.
so what the hell? I was thinking that I screwed the port of the phone with magnetics cables before read this.
Just my 2 cents here. Don't try to charge this phone with super fast chargers. Mine developed the well known fault that you needed to press the corner of the phone to get it to start charging. I even opened it and put a bit of a tape behind the ribbon cable connector (as some guy suggested on YT). It started charging again and then after a couple of weeks and a few more quick charges it stopped charging at all. I guess heat affects the connector or some element on the board. I've just ordered a new usb board and ribbon cable from Ali and if the phone comes back to life again I will never ever use the original rapid charger that came with the phone.
Using the charger tool that can be accessed with the *#800# dial codeI I have noticed that some old chargers that support Quick Charge 2.0 or 3.0 can quick charge my OnePlus 8T. I didn't expect this after reading that earlier OnePlus models didn't support Quick charge at all.
It quick charges with 18W 9V/2A or slightly less when the battery is not too charged already. I use a standard USB-A to USB-C cable for this. The phone only says "charging" but it is definitely a lot quicker than standard USB 5V charging. Charging always starts at 5V and switches to 9V after a while (less than 30 seconds).
I also get 18W 9V/2A charging with a USB PD charger and a USB-C to USB-C cable. In this case the phone says it is charging fast. I have not managed to get it to charge with more than 18W using USB PD.
With a (powerful) charger that doesn't support Quick Charge or USB PD the phone charges at 5V with only 0.5-0.8A current which is surprisingly low.
Does anyone know what charging standards that OnePlus 8T officially supports?
I was not able to reproduce your behaviour. Cannot get to charge faster than 10W with USB A cables or 6-7W with USB C cables. All of this was performed with various charger that support both QC and PD.
