Charging electronic devices in the field.

Charging devices on expeditions can be challenging. Solar devices can work well while 'in place', but are difficult to manage while moving and can take a long time for the device to charge. If you move during the day, you may find that the available solar power is limited to a short time, before and after hiking - and is insufficient to charge your equipment.  

Another option is a small pre-charged battery pack. If you are looking for way to quickly charge your smartphones & USB devices, I've found no better quality and value than the mophie juice pack powerstation® mini. This small pack measures 1.92 in x 3.64 in x 0.53 in and weighs less than three ounces. 

Battery capacity is 2500mAh which will charge my i-Phone 5s twice. Each charge takes approximately 25 minutes. 

The battery pack can be recharged via a USB port and is designed for 100 charge cycles. 

Currently the price is $59 and is available at www.mophie.com
