Review: These things are amazing, More people should know about them! - I have a buddy had this killer device charger he took with him on trips simply to have a large capacity for keeping his phone, laptop and things full. He spent well over $100 for it. I thought it was great. Here's the thing, it can’t jump start his car too! Here is my point, for well over 25% less cost, this device does the same thing, even has a larger capacity then his... AND... in a pinch happens to be able to both jump start my truck, but also act as a long lasting emergency flashlight. Why would anyone buy one of those storage bank device chargers when these things exist? 21000mah.. this will charge any device well over 5 times from zero to full. this is a must have! It works great, has two USb inputs for charging multiple devices at the same time, built well, takes only a few hours to charge... and keeps its charge for a VERY LONG time. don't hesitate. nab it. Great gift too!
Review: A true lifesaver! - First, the price is excellent. Second, it shipped right away. Third, it was packaged well. Fourth, the actual product packaging (carrying case, cables, etc.) is very good. Fifth—and very importantly—it came fully charged! That was a vital feature, because I immediately needed it to started my grandson’s car. He had left the car with me during his summer college break, and the battery died unexpectedly. The car (a 2018 Honda Civic) was parked in a place where no other vehicle could come near it for a jump start. Right out of the box, this handy little unit started my grandson’s car 3 times in 2 days. So I was able to start the car, back it out of its tight spot and drive straight to AutoZone for a new battery. Easy-peezy! I’m delighted with everything about this handy charger—including the orange color (which I love)! You can spend more … but why would you? Highly recommended.

### ⭐⭐⭐⭐⭐ Great little jumper box.
*by J***N on October 18, 2025*

I started using jumper boxes back in the late 90's when I transported autos. Then they were on wheels and took up a lot of space. I bought this because the price was right, and a friend had one like it. I did not think it would work because of my previous experience with the old style boxes. "NOTHING that small can jump off an F350!" Well, it did! I bought this, along with some cables to keep in my new pickup. So far, I have jumped off 2 motorcycles, 3 cars, 2 pickups, and a boat. (One motorcycle was mine, everything else were people in need.) It is WELL worth the money and is irreplaceable when you need it. It holds a decent charge for a few months, but I charge mine monthly. The trick is to let it sit on the dead battery for a few minutes, about 3 to 5, before trying to crank the dead engine. This is not an 'everyday use' item. BUT, as my old 1st Sergeant used to say, "It is better to have and not need, than to need an not have..." I hated him for making me ruck extra stuff, but, now that I am older, those are some VERY wise words! I would buy this again! It's worth the money!
