   I don’t let any of the family leave home without a battery bank jump starter in the car, in today’s world and this one is better than most. It does a great job of jumping your battery if you get stuck with a dead battery, however it also has a host of other uses that make it a great choice: 1) Jumps the battery quickly and efficiently. Worked several time on one charge 2) Can be used to charge multiple other devices including tablets, cellphones, airpods, basically, anything with a USB A port cable. I’ve charged multiple devices at once and it delivers. 3) Flashlight. Most jumping starting batteries have this, but not all are usable. This one does a great job of shining a bright light. It also does a flashing light, if you need one for a hazard light. 4) Recharges with USB-C. Many of these banks use a proprietary charging cable, which is a real hassle, since invariably, the cable gets lost and then you are having to order another specialty cable. 5) Has a LED display that clearly shows how much power you have left in the bank. Not a big deal but does help you quickly see if you need to recharge the bank, so that you are not stuck out in the middle of nowhere with a dead bank. This is a well thought out battery jump power bank, which does the job at a good price.

   Havent tried to start anything to crazy just yet some 6 cylinders with semi dead batteries and it did just fine. Its abit lighter then i expected given its claims however it hasnt shown any signs of being weak so i cant hold that against it if there able to get that power without shoving a super chunky battery/capacitor in. only down side is a only get a few hits out of it and then its dead

   Overall: A solidly built, easy to use, compact battery starter that has an excellent storage case. Good battery life allows multiple starts before needing to charge.

   What I liked:
   – Compact design. Light.
   – Excellent storage case.
   – Easy to read digital display shows battery life %.
   – Easy to use.
   – Operation requires minimal steps.

   Room for improvement:
   – Rubber covering for input / output connections appears flimsy. A plastic door with a gasket would be more durable.

   It’s been great really easy to use and a quick set up, the hard case it comes in is really nice as well

   While we luckily haven’t had to use it to jump a battery yet, we’ve already gotten benefit from it just from the peace of mind it offers knowing that it’s in the car if we need it. We have two vehicles but one is electric so jumping the other one isn’t possible, which I think is an ever-increasing problem in households these days as more cars are electric. This solves that problem while still allowing us to have an electric car but without the stress of not being able to jump the car if needed. The size made it easy to store out of the way in the car for emergencies so it’s always along for the ride.
