I made my shield remote rechargeable
Parts used
1 x AMS 1117 3.3V voltage regulator
1 x Charge controller - https://www.amazon.com/dp/B0836J8LR4?psc=1&ref=ppx_yo2_dt_b_product_details
1 x USB Type C breakout board
Adafruits powerboost charger would be better. The one i used doesn't output 5v unless a certain current threshold is met, or you push a button that only lasts ~30 sceonds. This is why I connected BAT directly to the voltage regulator and the battery. The voltage regulator might work as a over-discharge protection for the battery so I'm not too worried about this setup. The chip on the charge controller is an IP5306, which is terrible because of that design flaw. Apparently custom versions of this chip were made with an always on function or with i2c to set this, neither of which are features of the one shipping with all ip5306 products. All leds were removed from the regulator and charge controller to save battery. having them didn't meet the required current draw for always on 5v out anyways. I don't have a charge/charging indicator but idrc. Itd be easy to solder on an led but i dont want it.
Wiring is in pictures

Thanks for this guide, i've a few friends who are electrical engineers and could knock this out in 1 day for me.
HAS ANYONE ELSE MADE THIS OR DONE 1 OF THERE OWN DESIGN ?
I just used rechargeable AAA batteries... It was a lot easier

Wireless charging seems to be a new and fashion technology, cool and modern. But truthfully , this technology has been used for over 100 years in other areas, sure you’ve heard its name: TRANSFORMER
How does a transformer work? I’m sure you’ve learned on your physical class. Don’t remember? OK, check the picture below, it’ll help you understand.
This is a simple sketch map for the theory of transformer. Power transfer in 3 steps Electricity à Magnetic à Electricity. This is exactly how wireless charge works.
We have a transmitter and a receiver in every wireless charge situation. Only they are separated in a charge pad(transmitter) and a cellphone(receiver).
This seems simple, but it’s not. The most important places in this technology are:
1. Power --- transfer enough power for loader
2. Distance --- increase transfer distance
3. Efficiency --- decrease waste energy
4. Target --- recognize transfer target
5. Heat --- decrease heat while transfer
We now can get wireless power in a few situations, such as some electric vehicle, and cellphones. We believe that in the future, thank to our scientists and engineers’ brilliant idea and hard working, we may get rid of all cables and have unlimited power.

That's a good price for a charger of that capacity.
I received today the second charger I ordered for my brother.
Someone bought?
up! For those who have not seen, highly recommended!

Just wanted to chime in and say thanks, I bought one and it's amazing. Lasts way longer than I ever even expected it to, and it's not even that heavy.
The product was sent to me at a discounted price in exchange of a review, and this review is based on my own unbiased opinion.
So I needed a charger to use while travelling with many USB ports, and I found this charger from iClever that really seem's to be great.
The charger came in a plain box without much information, and inside of the box there was a manual, some information regarding their review program, a power cord and the charger itself. At first, I was surprised by how small this charger was and I really though it would perform badly, but I was wrong - it's the best charger I've ever owned.
So first of all, there's 6 different USB ports that can output up to 2,4amps - which means they're ideal for both phones and tablets. The charger have a feature similar to Ankers chargers, and that is a smart IC that monitors the charging and limits the output current for different devices.
So after using my XTAR power meter, I was able to get about 1,5 amps out while charging my phone - and that rate didn't decrease either after plugging in more devices. The voltage stays stable around 5v, and there's no dips down to 4volts.
So I've got no complaints really about this charger, and I really like this charger.

Today I am going to review LDesign Wireless Charger which is very convenient serving it's purpose. It is very light with a beautiful round shape and looks nice too. It has a micro usb port to connect to the charger, all one has to do is place the phone on the charging pad. It has non-slipping pads under so stays on the surface and holds it position. The charging pad also has non slipping ring set so holds the phone well.
Product Features:
Better temperature control
Charges as fast as wired chargers
Simple way to charge, just place it in the charging surface
Light indicators, when fully charged light turns off
Never overcharges phone
Adopted with the 3rd generation NPO
Technical Parameters:
Number of coils - 1
Charging distance - <5mm
Input voltage - DC 4.6~5.5V
Input current - 500~2000mA
Driven load - <=5W
Chanrging efficiency - 80%
Operating temperature - 0*C-40*C
Humidity range - 45-85% RH

Hello again! So you might know by now I am always in the market for power supplies that will trigger fast charge on a Nexus 6P, Google Pixel or Pixel 2 device! Well I found this cigarette lighter adaptor from Bestek that supplies more than 2.4Amp to the USB port plus has 2 additional cigarette lighter female sockets for more connections!
There are some better pictures on ebay than I could possibly take, but found it for a much lower price on Amazon if you are interested in snagging one of these.
I just upgraded to a Pixel 2XL and was very interested in how well it can charge my new device. I was unaware that the Pixel 2XL actually kicks into charge overdrive when you turn off the screen. So it took a while to capture this image showing it supplying 2.7 Amps!

Add to this, the capability of supplying almost 5 Amps total, and being able to switch each side off and on independently! You have a 12V cigarette lighter socket and USB port per side! Plus you have a display telling you how much current is being used! You can't beat this for the price!
