    It’s bulky but I expected that so it can have more surface area to collect UV Rays to recharge. Takes some time to recharge like that. It’s like a back up for me although it does hold power for while and can recharge my phone three times by itself. The clip on broke easily. Other than that I like it!

    Great power pack. I can charge my phone at least 3 times on this pack and it charges very quickly via the USB cable and will also charge via the Built-in Solar panel but much slower. I took it camping and it charged in about 4 hours in the sun.

    I got it on sale for about $25. Although I would say that it's still worth it even itf it's not on sale, because of the features. It's not just a battery bank that can charge my phone 2.5 times, it's got a big flashlight that has actually turned out really useful, can charge via solar (very slowly), and can hang from things, to charge from the sun if you're moving around.

    We charged four phones back to back without any trouble. The flashlight is really bright. We plan to bring it along for all of our rustic camping trips.

    Solar Bonus

    Very cool charger. I carry it around in my purse just in case I need it. One day I went out for a walk around our local lake park and realized my phone was almost dead. Broke out my charger and it was still fully charged even though I hadn’t touched it in about two months. So it holds its charge a long time. I haven’t really use the solar part yet to charge it. I charge it at home. Overall it’s a great charger and the solar charging is a bonus if you really need it. So far so good!

    Great charger. Very durable, but a bit bulky and heavy. It is better to charge it the night before use because solar charging takes much longer. This a great for travel use.

    One of the best I’ve ever used

    Love this backup battery. I don’t use the solar charging all the time. But I do like that I have it, and did use it when we lost power for 2 days. Was very grateful I had purchased this and hand it on stand by. Other then that feature it has a long charge. I was using it with a heated eye mask that’s on a timer. I like that when the timer shut off the battery did as well vs draining just because a cord was attached like some of the cheaper ones I have. I would happily buy more.

    Ultimate Portable Charger

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Charger was taking longer to charge outdoor. Was not fully charging. Maybe I should have left it longer. However, when I charged by plugging in electric outlet, it got fully charged. Loved that it has an LED light which will be helpful during blackouts or night walks. Have not tried charging cell or tablet so I gave it 4 stars. Hopefully, it will deliver as advertised.

    Great on the go charger for in the field. Rugged. Covered ports. Lightweight for its power and size. Price was reasonable. Does charge a bit slow.... recommend using as a full bank that can "trickle charge" itself while being used. Or, if using for camping/long excursions, plan your power accordingly.

    A really good resource for outdoor use. If you are a camper or hiker, this is a great charger. It does take a few days to recharge fully in direct sunlight, but it has been very durable. Definitely worth the purchase when you are miles from the nearest wall outlet.

    Solar Panel Charger

    The item will charge when put in the sun. It takes time to charge one bar. It charges faster in a wall plug. The solar panel should charge using the sun's energy when it is directly in the sun all bars should be full.

    Great deal with this solar charger. It charges really fast and I don't have to worry about "wasting" the battery by charging my phone because of the solar charging. Great buy and recommend.
