Charging problems

by Ryint on Mon Jan 02, 2017 6:44 pm

This is my second mintyboost build but for some reason the charging logo on my devices appears but the batteries drain instead of charge. Tried with fresh batteries on a Huawei p9 and iPad mini with no luck. Checked and double checked the board and there's no cold joints or shorts.
Any suggestions would be great.
Thanks

Not sure about the charge current requirements of the Huawei, but I believe that the iPad Mini needs at least 1A and the MintyBoost is only capable of sustaining 500mA.

I've since tried it with some older devices that worked fine with my first build and still had no luck. Could it maybe be a USB spec thing?

Check to make sure that the output is steady and close to 5v. Also check the voltages on the two data pins.
