Just a few quick specs and features before i get into my findings.
Specs:
- Capacity: 3000 mAh Performance for iPhones: 100% battery life
- Output: 5V / 1A;
- Size: 4.33" x 0.9" x 0.9"
- Weight: 3.07 oz.
- Warranty: 12 months
Features:
300 Mah battery charger
Hi - Beam flashlight
Low - Beam flashlight
Strobe mode
Removable clip
Observations:
- Both charging ports are on the bottom:
- Clip is removable if you don't like it.
- Glass of the front is flush. May cause scratching if placed face down
Pro:
- Despite being rated at 1A, my phone was charging at 1.9(Galaxy charge current) VERY impressed. (this was with included cable. VER high quality Micro USB)
- I feel that the design is very simple and gets the job done, it combines a power pack with a flashlight; with multiple modes so you do not need to use the one on your phone.
- The side is a little under 2 AA batteries and shorter than my standalone flashlight
- Auto on and off (Once a device is detected it will start charging and it will shutoff when it is unplugged) No more worrying about leaving it on.
Cons:
- No power status indicator. So you don't know how much juice you have left. I reached out the RavPower they told me that there was no way.
- Flash light button does not sit flush

This looks too much like generic chinese power banks with the RavPower branding.

this gives 2A charging. and is rated at 3000Mah. I haven't used those in order to compare.

Where did you buy the battery?

[Q] Tablet or phone as a powerbank

Hi. Is there any tweak or hack that will enable me to use my tab as a powerbank by using otg cable and usb cable. it is clearly that the power can come out from the usb port because it can power up a pendrive or for some tablet a hard disk. So it sound like possible to enable a tablet to become a powerbank.
Furthermore, is there any tweak that will enable me to transfer data from a tablet to a phone or vice versa by using otg cable and usb cable.
Thanks everyone.

asking response
anyone? or im just the one who in need of this...

Nope. There ain't no way you can use your phone as power bank meanwhile you can use its battery if you can remove that to get some power in your phone.. That works nice.
Why do you need to transfer data from tablet to phone using otg when you've got superbeam by the side.
Download and install suoerbeam you'll be addicted....

[Q] which forum for usb hub hardware-mod help? (otg+charging)

Which sub-forum can I ask a question about modifying this hub for OTG+charging ?
http://www.ebay.com/itm/Portable-Ho...-Cable-For-Samsung-Galaxy-S3-S4-/371129011472
I discovered after opening, that it only sends back 1.5 volts to the host, so it sends the 5v to the usb devices only.
Can I simply patch the red positive from the voltage input back the the red positive on the host? I assume they all share the same ground so that would not be necessary, unless the ground itself is being used to limit the voltage somehow.

Okay studying the back, it appears maybe I can just "jump" the positive from the 5+ input directly to the host 5+ since the ground is already shared.
The million dollar question is, what is that little part it is bypassing, capacitor, resistor, transistor?
And is it safe to apply 5v output to the 1.5v it is producing. I am assuming it is just a resistor knocking down the 5v to 1.5v ? What happens if you put 5v on both sides of the resistor?
for google to help find this later, is is a HUB-154A which is popular on ebay on amazon

Modifying HUB 154A to OTG+Charging
Hello,
I look about this because I bought the same for modify it to add charging feature.
The component seems to be a Jfet. The pin connected to the Led is also connected to Gnd.
I connected the hub to an Android device and tested wiring +5V from micro USB connector to +5V from external connected power source.
Nothing destroyed , but charging the Android device does'nt work .
I disconnected the external power supply from hub and the hub from Android device.
By reconnecting the hub to the device, Led will get on after about a half second. The time to know who makes what. So the device delivers +5V power supply to the hub and to the peripherals. In case of big energy-consuming by a peripheral, the external power supply is necessary.

Why do people like wireless charging?

I don't know if I'm the first one to say this, but I find wireless charging completely useless... I had an old '90s Motorola with a charging stand... I find that INFINITELY more useful than "Wireless charging".
First of all, the charger still has wires, so you're still stuck on a wall... Unless it has a battery attached to it, which is nice, though most scenarios where you use an on-the-go charger you are "on the go" and moving, so a normal external battery could do... (see third point)
Second. your phone is still during that time... You can't do anything to it... Why? Just so you don't need to put a wire in the port, to save some (1 second) time (?)
Third, it has ZERO stability. That's why I say that charger from 20 YEARS AGO was a lot better. You put your phone in and it charged. Same as Wireless charging, except that old Motorola didn't fall off and stop charging the second someone bumped into the table just a little bit. Or you are in a car...
I find wireless charging just good marketing taking charging a step back...
Also, the USB pins that keep the wire in my phone got crushed, so my phone right now can't be lifted while charging... PEOPLE ACTUALLY PAY FOR THIS???
PS: I found a "useful" use in cafes

All you need to do is plug in the phone and "wirelessly" charge....

I can't see the appeal, either. I use my phone a lot whilst it's attached to the charging cable. You can't do that when you use a wireless charger.
My charging cable is 2 meters long. I can sit on the sofa and use my phone as an ereader or TV screen whilst it's charging. If I were to use a charging pad, I'd have to leave it on the table, which is not very convenient.
For me wireless charging is just a useless gimmick.

I find the potential of it interesting, rather than the current state that it's in.
It just seems a billion times more durable than the damn micro-usb port on EVERY Android device.
Maybe wireless charging is the solution, or maybe it's usb type-c.... we'll see i guess :]

Yeah I don't see the appeal either. Maybe it's good for coffee shops or restaurants where you don't use your phone anyways and it's lying on the table, so might as well get charged.

Looking for a USB-C Hub with Power Delivery

I'm looking for a USB-C Hub with Power Delivery, any good suggestion?
I saw Choetech's official Facebook were given out big discount codes of its USB-C multiport adaptor, so I sent a PM to request a code. Anybody used this one?

Did you find a suitable hub?

Hi everyone,
I'm also trying to find a hub with different connector like HDMI / USB-A 3.0 / Ethernet... but it's very difficult to know if they are compatible with the Pixel C.
Most of them are compatible with Macbook but to few information about compatibility with Android.
Does anybody make a list of compatible hubs for pixel C ?

https://www.amazon.it/gp/product/B01CJMQZF0/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
I have this one. Of course look on it on amazon.com
It has ethernet,3hubs that i use with usb stick(fat32) to move my docs and has powerdelivery to charge while u work. HDMI is not supported with usb c yet.

A list I don't have but for a little over $11, I bought me this 3-Port USB 3.0 LAN RJ45 Hub (eBay Item # 162126608654) in combination with a USB 3.0 Female to USB C (Item # 152382378772)
, and my G-Pixel C is a happy camper so far

Also, a friend of mine has this one with power throughput to host, works great on my Pixel C too

I have one, it works. The HDMI doesn't work yet: but it's a Pixel C problem: see here

These claim Power Delivery.

Does anyone know of a hub that doesn't briefly disconnect USB devices (mouse, keyboard, Ethernet dongle, hard drive, ETC) if the charger is unplugged?
I have some cheap hubs and they work but if I unplug the charger then everything disconnects for a moment until the tablet can reconnect with its own power. This is not great for thumb drives!

As far as I know, all USB type-C hubs are like this. In fact, I think It's the intended behaviour. Switching from charger to device for power necessitates a brief interruption.
