    This is still my favorite portable battery charger. It is super durable and it is water proof. It holds a great charge and it does not take long to charge or charge my devices.

    This is one tough PowerBank. Recently used on an expedition sea kayak trip in a salt water, sandy environment. Kept my Marine VHF, GPS and other electronics charged for many days. It is heavy for its size but is about as simple to operate as possible. Despite being waterproof, it was kept in a protective case. I expect many years of service from this device. It is a bit expensive but I think it was worth the cost.

    I took this on a week-long canoe trip down the Missouri River. Since I only brought my phone (since it's my only camera) and a pair of headphones to listen to audiobooks at night, this provided ample power to spare. I like that it's waterproof, though I kept it in my dry bag the whole time, so I didn't need to see if that was true or not.

    It is very sturdy being waterproof and protects itself when dropped. It charges my phone a few times once it's full - but it takes forever to charge itself, hence the four stars.
