I have a pocket WiFi that supports reverse charging. So I plugged a dirt-cheap OTG adapter in, and a small LED lamp into that - and it worked. So I removed the LED lamp and plugged my Android phone in instead. That does not work. (The pocket WiFi doesn't charge the phone.) I also reversed the direction of the cable, which didn't work either.
Can someone recommend an OTG adapter/patch lead they know works for reverse charging a phone from a pocket WiFi?
Maybe the pocket WiFi doesn't output enough power.
Does it say in the manual how much it outputs? What model pocket WiFi and what phone?
