Bring power with you using the Power Plus 10 Portable 10,000mAh Battery Pack from Pom Gear. With 10,000mAh of power capacity, you don't need to hunt down an outlet every time your mobile device battery is depleted. This lithium-ion battery pack can recharge up to two devices simultaneously via the two USB Type-A ports. One port outputs at 5V/2.1A, and the other at 5V/1A, for a total of 3.1A of charging power.
You can recharge the Power Plus 10 using a car or wall charger (not included) and the included cable. Recharging the pack completely takes 5 hours, but it's pre-charged and ready to use right out of the box.
