“This item replaced a similar one we had that went bad. This item worked very well. It has a built in flashlight. It charged my phone a couple of times and I used the flashlight for several minutes before it needed a charge. It is charged by solar energy, obviously, but there is also an option to charge Any plugging it in to electric outlet. This is great for traveling and comes in quite handy to avoid having your phone attached to a wall to charge. ”
