The 38-kT MIYABI does not support quick charging. It accepts only up to 5V / 0.5A. If used with a quick charger, it will block the input to protect the battery. Check that your cable and power source meet this requirement.
Roughly 6 to 7 hours using a standard USB cable. High-resistance cables or non-standard setups may result in slower charging or incomplete charge (green light may continue blinking).
The 38-kT MIYABI uses a static touch switch. If your hands are dry, the switch may not register. Lightly moistening your fingertip can help.
Like a phone or computer, the 38-kT has internal circuitry that can occasionally bug. If this happens, remove and reinsert the battery to reset it.
