I would assume as long as you just tap the power pins it’s equivalent to wiring batteries in parallel (same voltage).
You’ll increase the available current but the device will only draw what it needs when charging. There should be no risk of overload if both are connected at the same time.
OK, so the only option is to plug into the micro USB port to give the power to the Android, and there’s not a way (at least as far as you know) of tapping into the power line inside of the device cavity to avoid having to plug into the micro USB port?
According to the post by @mobious, there is a point on the circuit board where you can solder:
I haven’t tried it yet to say for sure. This increases the distant from the charger so it may impact charging efficiency. It also is a more delicate process requiring trimming back some of the plastic on the Qi receiver USB connector. It would obviously void the warranty.
Update: I took the cover off a Fire tablet and put it over the one I made with the Qi receiver on the back and it seems to charge just fine. Thus, I think the extra distance won’t cause an issue.
In my case, they’re not Amazon devices. So, I don’t have that option…well, at least I won’t until I open one of mine up to see if I do Thanks for all of the interaction on this. I love seeing what you’ve done along this route already and I’m picking up good tips on my journey toward doing a better mounting job. Round one so far is just plastic clips to hold the tablet up there with the cable dangling down to where it plugs in. I mean, I’ve tried to hide it if there is anything else present that can run interference, but it’s far from a good, ‘finished’, built-in look.
They are pieces of garbage! I was part of the original campaign on indiegogo…for over 2 years they kept promising and promising and finally delivered a poorly built POS - one of them died after one use. Horrible product!
I came close to buying those but ended up going with SnapPower instead for my chargers (www.snappower.com) when they launched on Kickstarter. I was not disappointed at all! It’s a little different as it just provides a USB port, but it is very handy for renters who can’t go into the wall.
I’m thinking I may put this on my spare 42" TV and have a big screen, touch-capable SmartTiles device when it ships (currently targeted for March, but you all know how tech crowdfunding projects go).
I backed it thinking I might be able to find a use for it eventually. At worst, it was going to be a novelty item.
I got in at the Early Bird price of $99 (and an additional $19 later on for the camera add-on). It’s really the cost of a pair of cheap tablets. If it works, it’ll be awesome. If it doesn’t, at least it wasn’t the cost of their other device, the Pond (Touchscreen Projector retailing for $599).
Any thoughts here? Trying to change the “inactive” state of this button to also be a christmas tree. The active state shows as a christmas tree, and the title color change also works.
Very interesting that it still doesn’t work. It also seems to have overridden custom icons I had for a different tile below. (Both are back to the default)
Could this be due to the use of the important tags?
LOL! I made sure to update for my device ID. I’m a bit stumped. Seems to be just this time that is stuck. Adjusting a switch tile or a light tile seems to work in not active and inactive modes
