With 12500mAh at your disposal, you get large mobile power capacity plus the convenience of dual USB charging ports. Together, they deliver 2.1A output so you can power-up two smart devices at once to save time and keep going at your own pace. Plus, the P12500D has a precision digital display that tells you exactly how much charge it holds: no more guessing. As mobile devices become faster and integrate higher resolution screens, they also need more power – especially when we use them for high performance tasks such as gaming and ultra HD video.

No more flashing lights or vague bars – you get total accuracy and clarity at a glance. The P12500D holds enough power to fully re-charge a tablet 1 time, an average smartphone 4 times. That’s a lot of power on the go, freeing you from worries about empty batteries. Why waste time when you can recharge two devices simultaneously? The P12500D has two USB ports that output a total 2.1A. Recharge your smart mobile devices at once to reduce annoying waits and keep using both devices with no downtime.
