4.0 out of 5 stars Great Emergency Battery, But Not Necessarily Waterproof, 17 Aug. 2014
This review is from: Expower(R) Solar Panel Rain Resist shockproof Charger 6000mAh Portable Charger Backup External Battery Power Pack for iPhone 6 Plus 6 5S 5C 5 4S 4, iPad Air, Other iPads, iPods(Apple Adapters not Included), Samsung Galaxy S4, S3, S2, Note 3, Note 2, Most Kinds of Android Smart Phones and More Other Devices (Blue) (Wireless Phone Accessory)
External batteries are a must in my electronic-dependent life, and the addition of emergency solar charging makes this Expower power bank a real winner. Yes, the solar power panel is not as efficient as charging it via wall outlet or computer, but I was able to get a 1/4 charge in a few hours of direct sunlight, something that could be a lifesaver for a camper or hiker or anyone in the midst of a long power outage. With 5000 mAh of battery power, this has the ability to fully charge smart phones at least twice, depending on the phone. (Note: power attrition rates lower the actual available power for all external batteries. This one will charge my iPhone 5 with its 1440 mAh battery about two times, with a little power left over.)

My main concern with this battery -- and it doesn't limit the performance -- is the claim that it's waterproof. When I charge the battery in the summer sun, the plastic case buckles in the heat, and it separates on one side. It is impossible to snap the case together. When it cools, however, the case once again fits in place. The problem is that there is nothing between the case and the inner workings of the battery. The electronics are exposed as soon as the case is compromised. Even when the case seems to be tightly connected, I can see little gaps where water could get in. I would say that this battery may be somewhat water resistant, but not waterproof. If you are looking for an external battery to take, say, whitewater rafting, you may not be able to depend on it. Otherwise, this is a fine battery.

This charger comes with a carabiner-style clip (make sure the rubberized oval is securely back in place in the oval after you attach the clip), a short micro-USB to USB cable, and an old-style Apple adapter. The battery can be charged via USB or, in an emergency, partially charged in the sun. If you have a newer Apple lightning cable device, you'll have to supply your own charging cable.

This external power bank is a great choice for emergency power as long as you don't count on it to be waterproof. Note: I received a sample for review.
