Hi to everyone, this is my first post. A totally newbie.
And thanks to HJK for this fantastic review, looks awesome but still don’t understand some of these statistics :~ , I had to learn more :bigsmile:
I’ve some question about this battery box. I’ve the same (but white color), and bought on ebay. When receive mine, I had a problem with B USB output.
The B USB can’t charge Apple devices, and as HJK comments, the problem seems that is not Apple coded. Explained to the seller the problem and he sends me another unit with the same problem |( . The seller is asking the problem to the factory and he told me that they don’t know what’s the matter, really?
But maybe is not a problem of the unit, and the unit only can charge Apple devices in A port and should recode B port to charge Apple devices at the same time.
HJK, it’s possible to recode B port? Now I have two battery box that I can’t use B port.
Maybe you can answer a general charger/power pack question I have: My ZTE Engage smartphone is very picky about what will charge it. The two battery packs I have built already will charge the wife’s HTC One but not mine, my guess is because of something to do with the data pins. My power packs only use the + and - wires. So my question is about what certain chargers do to make the device it’s connected to think it’s connected to a computer, and how to know which chargers do that. Thanks!
Thank you for these great reviews HKJ. It really helps to get an idea of what these products are so we don’t have to order blindly.
I have a question about using cells of different voltages in this or other boxes. Why is this not a good idea? Shouldn’t they balance each other out since they are in parallel?
Also, would using different types/rands of batteries within the same box be OK? (eg Sanyo UR18650FM and Panasonic NCR18650B)
And lastly, Any chance that you could review this USB battery box?
