The Pipo Max M1 is an Android tablet with a 9.7 inch display, a Rockchip RK3066 dual core processor, Mali 400 graphics, and Android 4.1 Jelly Bean software. It’s about the same size as an iPad — and that means you can use some iPad cases with the tablet.
SlateDroid forum member Carnivore figured out that means you can even use an iPad case with an external battery to double the Pipo Max M1’s battery life… although you need to perform a little surgery.
The Pipo Max M1 fits snugly into the iP6000 battery case, but you may need to widen some of the holes in order to access the power button. But for the most part, if you’ve got a Chinese tablet that was designed to look like a first-generation iPad, it will probably fit the iP6000.
If you want to use the case’s built-in 6000mAh battery to charge your tablet, you’ll need to rip out the proprietary iPad dock connector and replace it with a power plug that you can connect to your tablet.
Carnivore didn’t stop there though. He also connected a full-sized USB connector and drilled a hole in the case so that it sticks out of the bottom. That way he can use the case’s battery not only to charge his tablet, but also any devices that have USB charging cables, including Bluetooth headphones, smartphones, or other mobile devices.
Without the battery case, Carnivore says the Pipo Max M1 gets 10 hours of run time when reading PDF files, but just 3 hours of run time when playing games at full brightness.
After modifying the case for use with the tablet, he says he gets up to 17.5 hours of reading time and 5.25 hours of gaming time.$30 from eBay.
