Examples of wall-mounted tablets - charging options


(Crispin) #1

I’m curious to see what others have done with charging solutions for wall-mounted tablets.
Personally I hate wires and don’t want to see them.

I’ve used a number of these

and


Mostly because you cannot see them when plugged in. They’re very discrete.

and the power the the charger is brought up through the wall. The tablet is then velcro’d onto the wall.
Finished Item:

and when removed:

My biggest issue with this is power. The tablet, when on full-bright draws more than 1A. The wireless charger can only muster 1A.

I have it dim when there is no motion or activity but when the house is busy it does not get much of a chance to dim so eventually flattens the battery.

What have others done to solve the power problems?

I use a Teclast P10

It supports charging via a DC jack and USB. I opened up the case and fed two small wires into it and soldered them onto the relevant pads. The wires then have a small connector to a powersupply in the wall.

This tablet run 24x7 using Imperihome as the UI. I have an app “Target Home Launcher” which allows me to set Imperihome as the Android Launcher.

Works great and battery always at 100%

I’ve not actually thought of doing that. Could be done with the tablet I have.

I’ve done something very similar to this. I’ve added the wireless charging coil on the inside of the Samsung Tab A10 and soldered the coil wires directly to the usb port on the inside. So from the outside the device looks unchanged. On the wall i mounted the wireless charger with 3 coils, bought from AliExpress.

At first I wanted to mount the tablet using strong natural magnets on the inside of the carging device and metal plates on the tablet, but this didnt work too well, so now new idea is to create a 3d printed cradle that will latch onto charging device in either horizontal or vertical orientation. I can maybe post some pictures soon.

I have around 12 tablets around the house, many Lenovo Tab3/4 7" and 10", a few Huawei, and a Samsung (still under tests).
I remove their batteries, but I still keep the small battery pcb for the thermistor and id pins, add an Arduino ProMini to power them on after a power loss, add some wires for power. Most of them don’t have the back anymore, I want them to be as slim as possible, under 9mm.
