Portable Car Jump Starter - 5000A Peak Current (Up to All Gas or 10L Diesel Engine) 12V Auto Battery Booster Portable Power Pack with Indicator Light Jumper Cables, QC 3.0 and LED Light

Works great!!! Hooks up the portable jump start and back in the road in short period of time. Looks well built and well packed. Also can use it as an additional power bank. Lighter parts is useless for me since I don’t smoke. But always good to have additional accessories just in case.

This is my second of these units. Great value for the price. No problem starting any engines I have. Much easier to keep in the vehicle because of the small size.

Have you ever drained a battery in the middle of nowhere? I keep these in the cars and teach the wife and daughter to use them.. A sure way out of a dark parking garage or darked street.THis unit is well built, feels of quality and has great features. It serves as a flashlight, and can charge your phones as well. THis unit is charges with a USB-C so thats great too. I am amazed about how much power these things have. You be surprised.

I was having issues with my motorcycles charging system and found myself stranded multiple times during test runs. This is bigger than I anticipated but it still fits in my bags and held enough of a charge to get me home when needed. Now with the cold winter months it'll stay in my van, just in case.

The description on this jump starter is very deceiving, it's supposed to jump start up to a 10 L diesel, but it won't jump start anything if it has a fully dead battery, it has to see voltage to determine whether you have the cables hookup correctly the downfall is with no voltage in the battery it won't jump start. I don't see the point,

I want to get a jump start in case of car battery breakdown. I want to get a good amount of energy of 5000 amp at affordable price. I tested this product and it did great in jump starting the car.

Works great my husband has used it twice now and worked like a charm. Holds its charge too.

Yes, the POWESU Portable Car Jump Starter is a power bank too, but I only selected it to be a jump box. In general, these devices make me a little nervous. The surge draw is high, but I guess that's mitigated somewhat by the EXTREMELY short jump cables. This is good for allowing a smaller conductor diameter, but the cable is so short, I don't think it will reach the terminals of a 94R battery. Fortunately, I only need to use this on batteries in the group 24 size range. I jumped my big Generac generator (3L). I've also jumped an R35 and a C32. No issues. The jump dongle has the protection circuitry built in to it, and the thing will lock you out after you've drawn a certain amount of power, in a certain amount of time. This device has pouch cells and an unknown BMS, so I'd be super careful about overcharging, overdischarging, using the device when it's too cold or hot, or storing it in high heat (which I think would preclude you from keeping this in the car full-time.As a battery pack, this seems fine. Charging via USB-C is quick enough, and USB-C PD back to my phone works well, too. If there's an issue, it would be the price. With the $20 coupon (available at the time of this review), you get an $80 price. Even with the discount, it's not exactly a great value. Peak current is supposedly better than some products in this segment, but I will say that it seemed close to its limit in trying to start 3.0 and 3.8L V-6s. Could it have handled an engine with greater rotational mass and cylinder count? No idea. I wouldn't count on it.
