Update: This deal has ended, but this item is still available for just $11.

Manufacturers have finally started putting more focus into the battery performance on smartphones, but often times with how busy we are they still don't meet our needs. No one wants to sit connected to a wall to get extra power during the day, and luckily you don't have to. Portable batteries are an investment everyone should make, especially when they are this inexpensive. Right now you can pick up a 10000mAh battery pack from Kmashi for just $7.99 with coupon code 5EX29OBF at Amazon.

This is a discount of $4 off its regular price and brings it around $1.50 lower than we normally see deal prices on it for. It has 2 USB ports so you can easily charge multiple devices at the same time (outputs at 2.1A), and the built-in LEDs show you how much power the battery itself has left. Want something even more portable? This 5000mAh battery pack can easily fit in your pocket, and it is down to just $5.99 with coupon OIJ89P7C.

If you struggle to make it through the day with your battery life or need something for when traveling, you won't want to miss this deal.
