Having an iPhone, Android smart phone, ebook reader like a Kindle, or other type of mobile devices can make you more efficient, more in tune with your friends and family, and keep you up to date. But what happens when you are running low on power for your device and you aren’t able to charge it? USB Batteries are external battery packs and chargers that will power and recharge your devices anywhere without access to an electrical outlet.
They 4 key things to look for in a mobile device battery pack are:
- Power – How much power do they store?
- Size – Will it fit in the space you have for it (in a bag, attached to device, etc)
- Connections – Will it connect and power your device? How can you recharge it?
- Durability – These things will travel with you and need to be durable
Based on these criteria, here are our top five USB battery chargers for your mobile devices:
5 – First up is the Splash Intense 5400mAh External USB Battery Pack. This small unit weighs in at providing 5400 mAh of power which is going to be several recharges for today’s smartphones.

This is easy to use, has a large power capacity, and is a stylish unit to carry around with the many connection tips that are included making it a great buy.
4 – Next on our list is the Energizer XP2000 Universal Rechargeable Power Pack. This tiny unit has lots of things going for it.

This is a great unit for those who need an occasional extra boost to their iPhone, iPad, Kindle, or other mobile device and aren’t sure if they are going to be outdoors, in a car, or by a computer when they need it.
