Hello Friends, I cant understand why USB LED not lit up. when I insert in to PC usb port, it runs nicely. but when I insert in usb charging adapter and try to run. it cant. does it require few mili amps? cant it take few mili amps form 1Amp?
i can charge my ipad with this adapter, its works nice.
So can I but it takes its time to charge.
These chargers in the pic are dangerous crap with no protection.They also have the problem that they only work with a sufficient load and the response from a phone / tablet.Let me elaborate:The power supply checks if power is actually needed, when you connect a phone it demends a lot.With no load the adapter goes into standby mode - either providing no voltage at all or just a teat voltage to check if something is connected.You light has not enough power consumption to work on the adapter.With just 30mA the adaptor won't recognise the demand for power, although it is always best to actually measure what is happening. ;)
It sounds like the charger does not have enough current.
