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)
Has anyone found any cheap chargers that can charge this phone like the Essential charger does (really fast)? I have bought two different chargers and neither of them can really even charge the phone. The lock screen says it's charging slowly, and the battery meter acts like it's charging, but it doesn't actually charge. The chargers were both Quick Charge 3.0 chargers too. None of my old phone chargers with a type-c adapter will charge the phone either.

Have you tried different cables?
Every charger I own will charge this phone. My Samsung, pixel, Motorola, etc usb type-c chargers will all work.

The phone requires a USB PD (Power Delivery) charger for rapid charging. It must have [email protected] and [email protected]
It doesn't support Qualcomm's Quick Charge.
I ordered this one and it rapid charges. It supports 5V/3A, 9V/3A, 15V/ 3A, 20V/2.25A

Thanks! Now, what about if I wanted it to just charge normally (not rapidly or slowly) for if if I wanted to leave it charging overnight? Don't think I need to spend the extra money on rapid chargers for that scenario...

No idea. Honestly, I don't know of anyone who consciously needs to control the speed of their charge. I avoid charging overnight by rapid charging during the day at work.
does it really need PD? they are kind of expensive and there are chargers out there with 5V, 6V, 9V, 12V @ 3A

Then why does the phone indicate it's rapidly charging when plugged into a QC 3.0 charger then?

I'm not sure how Android is programmed to display "Rapidly Charging", but I'm sure it's not by charging standard. Probably based on supplied power, but it definitely doesn't charge as fast as the stock charger. I noticed this with my QC chargers. It will say rapidly charging for a couple minutes and then just not charge at all or say charging slowly. Frustrating as hell so I bought an extra USB PD charger.
My Samsung chargers all work, and charge the phone to 100%. They just say charging, not quick charging, but whatever... The % goes up.

Try using the Ampere app on the Play store. It will show you what amounts of current etc is being used to charge the phone..

I ordered this. Won't be here for awhile though as it's coming from China. I brought the essential because it was cheap, might as well stick to the theme.

Yeah...it doesn't. I'm such a tool I assumed it did and bought two Ankar QC3 wall chargers and a Tronsmart QC3 car charger. None of them are able to charge the phone at all, says that it's charging slowly but doesn't seem as though it's charging at all.

Phone needs a charger with USB-C Power Delivery and not QC. Anker has at least one model and Incipio has one as well. There are many others on Amazon.. The cool thing about those is that they also change my XPS-13. Only carry one charger when I travel.
I've got a few QC 2/3 chargers and a few USB-C PD chargers and what I've found is that depending on which USB-C to USB-A makes a difference whether I get rapid charge or not.
I'm slowly converting over to USB-C to USB-C but it is stupid expensive for some things like the power packs with USB-C...
Anyway, try a few different cables and see if it works for you, also it seems to work a tiny bit better on the Oreo Beta however my QC 2.0 car charger doesn't charge as fast as it did on 7.1.1 but luckily the car chargers are the cheapest USB-C PD items to buy, roughly about the same price as a cable.
One last note, the same charger and cable don't always go into rapid charging mode so replugging the cable in sometime kicks in rapid mode for me.

Haven't tried it, but something like this with USB PD sounds like it would be good - https://www.amazon.co.uk/Charger-Delivery-Output-Adaptor-Samsung/dp/B01M2BLLVN/
I had my phone plugged into a regular USB jack on a car this weekend and the battery didn't charge at all
Alas, not available in the US...
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.
So, when it is about charging, this Galaxy S21+ (Exynos) can be really choosy. With a lot of chargers, it difficulty reach 1.3A. Only few of the selected chargers (my Lenovo 65Watt laptop charger, IKEA 27Watt charger) it could reach 2A charging with wired. For wireless charging, it's even worse. Currently I owned 3 wireless chargers.
1. Energizer 15Watt charger. Never even shows Fast Wireless Charging.
2. Samsung EB-U1200 Wireless Charging Power Bank. This one shows Fast Wireless charging. It could charge up to 2A for a while and then once the battery temp hits about 39C (and it hits there within 5 mins), it throttles.
3. Huawei SuperCharge 27Watt Wireless Charger (with Huawei 22.5Watt SuperCharge Charger and 5A cable), performs same as Samsung Power Bank. Reaches up to 2A, then battery heats up and throttles.
I've tried different ways, including removing the phone case while charging but result is still the same. Does any of you have similar experience? or is it just my phone? Please advise me how to make wireless charging more efficient.
I've not tried wireless charging however for wired you need a charger that supports USB C PD PPS (this is a fairly new standard) and without this you won't get anything more than about 2A.
This Ravpower charger for £16 (£13 with current voucher code) works a treat hitting 4.6A when the battery is empty reducing as the battery becomes full. You have to use USB C to USB C to achieve this.
