SOLVED: USB OTG cable not charging phone

Do you have a USB OTG cable with power connector that doesn’t always charge your phone? This is why…

I tested this out after seeing some reviews on Amazon for this Kimilar OTG Cable with power pass thru (a.k.a a Micro USB Host Cable) which charged perfectly for me while a USB keyboard was plugged into it, and working.

Turns out you need to make sure that you plug your charger cable AND the USB device you want to connect into the OTG cable before plugging the OTG cable into your phone and then it works:

USB OTG Charging not working on Samsung Galaxy S7

I’ve been contacted by Garry who’s been experimenting with a selection of cables like this. He can confirm that there is something peculiar about the S7 Edge and no matter which power pass-through OTG cable he uses it simple will not charge the phone. This suggests Samsung have done something to stop this working. Therefore it appears that some phones, although compatible with USB OTG for connecting external devices, do not allow charging at the same time. If you know of any tips to get around this please comment below.

      It seems that there are some phones where the OTG and charging don’t work as I explained here – plugging charger cable AND device you want to connect into the OTG cable BEFORE connecting it to the phone. If you did that and it isn’t working then perhaps your phone is a Samsung! (See other comments here about Samsung phones and the note at the end of the article above).

    Other sites say you have to plug the charging cable into the hub before plugging the hub into phone.
    However I have a Samsung S5 and cant get it to charge at all via the hub even though the switch is on charge. Plugging in USBs work ok though

      It appears that there are issues with Samsung phones and OTG charging according to some other comments I got here and some emails I received on the subject. Can’t help with that I’m afraid.
