    I hooked up one of those current readers in between the tablet and adaptor. Now the adaptor can output a max of 3A but I see my hi12 is only taking in 1.38A.

    Is this normal? Charging seems slow. How long should it take to do a full charge from empty?

    Also it shuts down when at 20%. Is this normal?

    Thx

    Yes, that’s about right for the charging current, maybe they limited it to protect the power management chip. Mine can reach 100% overnight (mybe 8 hours, didn’t time exactly). For the power off problem you might need the BIOS update, have a look at the thread in the sticky section of the forum.

    Nowadays, usb cables and usb chargers are very bad … first, you should buy a usb resistor in order to check if the charge can provide 2+A.

    After that you need a thick usb cable which performs with 2A.

    Buy a good thick micro usb cable and check ūüėČ one night is enough for me to fully charge the chuwi.

    The quality and adaptability of USB power supplies varies¬† considerably, unfortunately. Using the shortest, thickest USB cable I have my tablet, which is almost fully charged, is drawing between 9 and 10 watts measured at the wall.¬†That’s all in line with a 2A draw.

    Plugged into a USB power distributor that works really well with¬†a variety of high drain devices Battery Bar was reading 950mW charging. :shrug: I can’t measure that one any better since its hooked up to a 12v DC solar system. I’ve seen it go as high as ~1200mW charging in the USB distributor but only when the battery is fairly low. That’s around a 3A draw while the tablet is running.
