I lost my AC adapter

Hi,

There are two ways that you can charge the tablet.

Either with an AC/DC adapter with an AC voltage and input plug design dependent on your location and having an output of 5V DC @ 2.0A and a DC barrel type output power plug (2.5mm).

The alternative is to connect the tablet via a USB cable to any known working computer's USB port or even connecting a mobile phone charger which has a micro USB connector attached.

Be aware that using the USB port charge option, charging will take longer as most computer USB ports or phone chargers only supply 5V DC at 0.5A.

Here's an image to show the two charging options for the tablet.
