Solar Charger, Power Bank, 42800mAh Portable Charger Power Bank External Battery Pack 5V3.1A Qc 3.0 Fast Charger Built-in Super Bright Flashlight (Black)

This power bank has a super large capacity! I charge it over night and have more than enough power to run two cell phones / tablets all day long. The solar cell is a nice plus to help keep it topped while at the beach or even while it sits on a window sill (but will take longer to charge via solar panel). There are LED indicators to show the charge level (25%, 50%, 75% and 100%) of the battery pack. Charging the battery pack requires a USB-C cable connected between the middle connector on the pack and a 5VOLT / 2AMP (or greater - 3.1AMP is ideal) power supply and will take a little over 10 hours to fully charge. The output of the battery pack is via (2) traditional (older) USB-A jacks that permit powering / charging 2 devices at once. Included is a woven strap and carabiner to make securing / hanging it easy. There is a bright LED that can come in handy, too. The only drawbacks are the weight (large capacity battery packs have some weight so it's hard to have one without the other) and the power output could be better. "PD technology" was in its infancy when this came out. Regardless, it seems to keep a cell phone battery charge FULL while connected and being used. A partially depleted cell battery does charge rather slowly through this battery pack.

If you're someone who's always on the go and needs to keep their phones charged, then the battery pack is definitely a must-have. I recently got my hands on a battery pack that has completely exceeded my expectations in terms of performance and reliability.One of the best things about this battery pack is its long-lasting battery life. It can easily last for several days without needing to be charged, which is great if you're someone who's constantly on the move and doesn't have access to power outlets.Another great feature of this battery pack is that it can charge two phones at the same time, which is a huge convenience. This means that you can charge both your phone and your friend's phone at the same time without having to wait for one to finish charging before you can charge the other.The battery pack is also very compact and easy to carry around, making it perfect for traveling or just running errands around town. It fits easily into a purse, backpack or even a pocket, so you can take it with you wherever you go.Overall, I would highly recommend this battery pack to anyone who needs to keep their phones charged on the go. With its long battery life and ability to charge two phones at the same time, it's definitely one of the best battery packs on the market today.

I lately received this product. I had to use it as soon as I received to inflate my son’s soccer ball. The product is so easy and comfortable to use. It can be use for anything you want like car tire, as a night light in emergency and multiple uses. Also it is solar charging bank. No power consumption!! I highly recommend this product to everyone! For both indoor and outdoor use.

As my title states, this does charge in daylight but it also takes quite a bit of time. It also does charge from other sources, a wall outlet. I haven’t tried anything else like a generator or anything also it has a flash light on it. Kinda redundant if you have a smartphone. Anyway it holds a nice bit of energy. The strap it came with isn’t the greatest and I already broke it. But that may have just been me. It’s kinda bulky and most likely won’t fit in you pockets. It’s still an energy bank with big battery and can charge from solar but not fast. It was worth it in my opinion.

Works good, Charge lasts along time. Perfect for camping or sitting at the ball field. Is heavy but its manageable.

Disappointed. I’ve had this unit for about a year and rarely use it unless I’m traveling. The case has come off slightly and now I am unable to plug in the USB or the C plug-in at the end. It’s almost like the case has shifted off the unit. I’m sure it still works, but there’s no way to charge my unit. I do like that it can charge by sunlight, however, I do not like the size of the unit.

Very functional. Time and life saving. Can charge a phone, portable speakers, and even caping devices, worth the money.

I'm having trouble getting it fully charged. It WAS fully charged. Then I used it and I've had trouble with it. The flashlight works, but I needed it for the cell phone.
