This is one of my favorite things. I leave it in the car and let it charge up the disappointment. Part is it doesn’t hold a charge very long. Read more

This product works great with a wide variety of tools on it. You can charge your phone with this product. And if it's dead, it charges up very quickly. Long battery life. The Solar panel is OK not crazy but if you are in a bad situation, it's awesome to have. One of the best things is it's waterproof too so you don't have to worry about it getting as damaged when you're out in the elements. Read more

This 20,000mAh solar power bank is an absolute must-have for anyone who spends time outdoors. The battery capacity is fantastic—it holds enough charge to power my phone multiple times during a camping trip. The solar charging feature is super handy in remote areas, and while it’s not as fast as plugging into an outlet, it’s a lifesaver when you’re away from electricity. What really impressed me is its rugged design. The waterproof and shockproof construction makes it perfect for outdoor use, and it has withstood a few accidental drops without any issues. The built-in flashlight is a great bonus, especially for emergencies or nighttime use. Overall, this solar charger is reliable, durable, and incredibly useful for outdoor activities or as an emergency backup. I’d highly recommend it to campers, hikers, or anyone who needs portable power on the go! Read more

Brought it on camping trip and it's battery drains really fast and the solar charging isn't viable imo takes forever to charge up better to charge it up in an outlet and and just use it as a flashlight. Read more

This review covers the power bank supplying power to the GL-MT3000 vpn router also purchased from Amazon. The GL draws 4.92 volts at 0.56 amps thus pulling approximately 2.75 watts. Using these numbers the 20000 mAh battery in theory should power the router for over 37 hours. After using this power bank the first indicator led turned off after the first 2.5 hours. I did notice the weight of the power bank as well as it's build quality. As far of the weight it is not as heavy as a 20000 mopie power bank I currently have had for a couple of years. The build of the unit seems to be kind of the middle of the road. One thing that I have notice is that this is a Lipo battery according to the documentation shipped with the unit. However, information listed on the website defines it as a Lithium-ion battery. That being the reason that I ordered this unit in the first place so beware. Now haveing this unit I did do some research as to the safty of this battery type. One thing I have done with each battery pack that I have purchased for Lithium-ion as well as this power pack is the safty bags for when storing or traveling with power banks as a safety precausion. Now should the power bank actually last for the 37 hours take away an hour or two. It will provide the runtime I was looking for should I get stuck in an airport without access to an electrial outlet I can still use the VPN router to connect to public wifi without having to worry about security. As a side note I have setup VPN on the router using Proton's `VPN free option using Japan, Netherlands as well as USA for locations. Overall the router along with this power bank will give the average user the ablity to share with others in their traveling group a worry free wireless connection via VPN. I am looking to see if the solar feature of this powerbank will help with the unit by providing a trickel charge during it use within the airport. This should work if the light source is strong enough to provide what is required by the solar screen to charge. Read more
