EverStart Maxx J5CPDE Jump Starter and Power Station, 1400 Peak Amps, 500W Inverter, 120 PSI Compressor

Product was in stock which was great for an emergency jump start of my wife’s car. Very reasonably priced. It came with a “full charge” that allowed me to jump the car, then only took about 18 hours to fully charge. I have used it two additional times for jump starts and a power bank, and it still indicates a full charge. Great jump box for the price

honestly didn't have high hopes for this thing as I had left my light on for days and thought I had liked my battery completely. I charged this overnight and it started my battery with no problem. I will say following the instructions of not putting the other cable on the battery and instead grounding it on metal on the car didn't work. it wouldn't throw the correct connection signal to jump it so I had to connect both cables to the battery.

My Everstart 750 jump box finally quit on me after a few years. For you who don't know that's the red one that cost less than this one . Alot less. But it got the job done . Had a little extra money this time figured I get more power. Less charges. So far charge it once and not even looked at the charge meter. I jumped my 800 cca amp battery off twice. Aired up 2 car tires. And it's been in my car since day one in the cold. But this is wear it showed it's muscle,. Couple of weeks back I was at Walmart shopping and when I was walking to my car a lady ask me boost. So I grabbed this box that I'm writing the review on and she said " No I need someone with booster cables, Those things won't crank my Truck " . I said know one had this one and we kept waking to her Truck. Big four-door Denali with the whole package if add on power eaters . Remember now it's been in my car for weeks and I still haven't checked the power meter to the day. I didn't have anything on the line but if it wouldn't have crank her house on wheels . I Would have went in the app and returned it immediately after it failed to crank her car. Now the lady said all week she been getting a boost when she cut it off every time. So she would have bet money that it wasn't going to crank her car. She probably done seen 10 jump boxes in that week. She had gotten to the point where she only wanted it crunk with booster cables. She didn't want to waste an time playing with no one else jump starter. No that 750 I had before this one . I think it would have worked but it wouldn't have worked after all this time in the car that this one has been. On thar 750 she would have gotten a good draw off it . The 2 hit would have been useless. To me , this one was wanting more cars in a row needing power from it . Hold up I'll be right back . Finna go check the power meter. Alright. 4 out of 4 full bars resting 12.6 and it's in the 30s outside. I think it's been in there about 5 weeks. . I recommend this starter over Temu and Harbor freight if I had my family in the car. I'll never get a pocket jumpstarter for reliability, From now in this one will be the base for me . I like power

I purchased this because I have an older truck with a huge engine and I live in the Midwest where it gets to be sub-zero quite often and I don't have room to park my truck a Yukon Denali XL in the garage with the other cars so this jump starter pack came in super handy as long as it's fully charged I have found you can get two charges out of it without recharging it plugged in and it has worked without fail I used it the very next day after I purchased it and it was a lifesaver I would highly recommend

I cannot rate the jump starters battery life this review is for the use of the jump starter. I had a dead 2003 Lexus SUV and I needed to move it for the street cleaner day. So I bought the item, charged it and jump started the car on one day and used it that evening to jump the car again and move it back. The starter operated great, no problems either time. It did NOT augment the car battery (it didn’t add to the car’s battery reserve at all). I mention this as some people tell me that their car battery seemed to receive a charge from the jump start, my Lexus did not. It was as dead after the jump as before.

It’s a very heavy unit that doesn’t really run much if you plug it in for say a floor fan or something it’s not really a power station. It’s OK to jump the truck. It will fill four tires but the battery life is crap in the amount of energy is not enoughdefinitely not worth the money.

this isnt worth the money and doesnt provide a way to charge it back up. you have buy something like extension cord thats small to fit in the wall of it where plug in is cuz you cant plug it in outlet or surge protecter dont fit either. if i could of returned it i would have for not having a way to charge it. i just ordered a smaller one and hope it works to charge, but dont recommend due to how hard it is to find something to charge it

First thing instructions say is to plug in and charge for 40 hours. no power cord to charge it. no mention on box or description. no suggestion tonorder with a power cord. had delivered to hotel day bc my battery died on Thanksgiving. to be fair the indicator light said it was charged. i am returning bc by the time ypu add the cost of the cord ordered separately there are better ones for less.

This unit can start a 4 cylinder and maybe a hot V6 engine but can't start a cold V8. I've tried it on two different V8s now. With weak (not dead) batteries this jump starter could barely make the engines turn over one or two slow times. A comparable Shumacher jump starter spun them easily to crank them. Hard pass on this unit.

I don’t know if it’s because I was given an obvious return that was damaged somehow or if this power charger really does suck as bad as it appears. This won’t even charge a laptop to 80% before it’s dead. That’s with a full charge. I can do that with the free power bank I got as a “gift” from the casino. This thing is a joke. Billed as “for emergencies” but will get you through 45 minutes before it’s an 8 pound paper weight. If you have an ACTUAL EMERGENCY, and you’re relying on this, you’re cooked. I can’t even imagine how this would restart a car battery in f it can’t handle powering up a netbook fully. This is not for emergencies. This is for privileged, pampered campers who want the appearance of being rugged while sleeping in their glamping tent with fairy lights and nonsense hanging around for an Instagram shoot. This is not a serious product.
