SUHU Car Jump Starter, 1500A Peak Car Battery Jump Starter (Up to 7.0L Gas and 5.5L Diesel Engine), 12V Jump Starter Battery Pack, Battery Jumper Starter Portable with 3-Mode Light & 5 Charge Ports

This thing has saved a few moments by being able to start my and others cars when needed. No complaints. Nice to be able to use it as a random battery charger too, I guess, though it doesn't last as long as you think it might. Reasonable size for the primary function, not so much for a pocket charger. But that's ok! I didn't buy it to charge my phone. Car appreciates it. Does what it's supposed to.

Your EV has massive battery to drive 300 miles but doesn't start because it still has a dumb 12V to actually start the vehicle...no idea why but leaving auxiliary on for even a short time kills my Kona EV.Ordered this jumper kit. Same day delivery. Charged it and jumped my dead cars within hours of it quitting on me. Just what I was looking for!Pay attention to the other advice I've seen that it uses USB-C cable so if you use a 1amp plug it'll take like 9 hours to charge, 2amp is 6 hours and 3amp 3 hours or so. I was concerned at first because it seemed to take a long time to charge but changing charges was illustrated by a faster blinking blue light so does give feedback.Most of the time that's not a big deal but since my EV went flat in a parking lot where I couldn't easily access jumper cables from my other car I was counting on this right away. In future just plugging it in overnight should last for months.Have already jumped car twice and works instantly. Nice to have until I buy another auxiliary battery.Comes with a booklet with all instructions but it's super easy. Don't even need to turn it on to jump car, just plug in cables and it's ready to go. Excellent product over last two days of use. No idea how long term but so far so good.

Nice-looking little unit (cute, even) with a great carrying case. Was a bit skeptical as to how well this thing might work (having never used one before), but by golly it started my truck up INSTANTLY after my battery had been completely dead (to the point where I only got a clicking noise when trying to start the vehicle). There were more expensive units offered by amazon but I didn't want to spend a fortune. This one was more moderately priced but got the job done just fine, and so was well worth the money spent and was a good value.Note: The jump starter needs to be charged up before use, but comes with a USB cord only, so you won't be able to plug it directly into a wall outlet. You'll need an adapter. In my case, I didn't have an adapter so I plugged the cable into the USB port of my computer. This worked just fine, and the unit was fully charged in about two hours.Another note: The instruction manual is worthless. It was obviously written by a person for whom English is not their primary language, rendering the manual pretty much useless. Not a huge deal. I just wish they'd hired a proofreader, as this was my only complaint. Still gave the product five stars, though, because the thing worked so well.

Those that rated this product 5 stars are probably more write than me. I rated it less than perfect because I had problems getting it to charge my EVs 12 volt battery but after many tries I did finally succeed. But I suspect the real problem was just how bad my 12 volt battery was. The problem probably is the fault of my Fiat 500e which didn't give any diagnostic warning until that battery was so far gone that it had visibly expanded in size and my EV could not start without a jump start. Also since EVs don't need any cranking power to start, a 12 volt battery can be far more degraded and still start the EV ok. So when I first tried the jump starter it gave me the "REVERSE POLARITY OR SHORT CIRCUI" error. I got past this error but connecting the + to + and - to ground after several failed attempts at connecting + to + and - to - and getting the error. However, connecting - to ground only got my EV to start to come on but then shut off. But apparently this also fixed my reverse polarity problem because when in frustration I again tried + to + and - to - I was able to start my EV. But even this didn't work the first time and wasn't consistent. But I did succeed in getting my EV started and drove it to a repair shop that replaced my 12v battery. Now my EV works as normal with the new battery. The reason I tried + to + and - to - is because that is how a tow service got my EV started before I bought the jump starter. The reason I tried + to + and - to ground is because that is how my Fiat manual says to jump start it. The first time I tried - to ground I got a spark like one would get connecting jumper cables backwards (but not as strong a spark). The combination of the reverse polarity or short errors and this spark makes me think that in the time that I waited for the jump starter to be delivered that my 12v battery went from little to no charge to reverse polarity. But it would be hard for a gas car to have these problems because the battery would stop being able to crank the car long before the battery is so bad that it has no charge or reverses polarity.

SO GLAD I PURCHASED THIS ITEM IT HAS WORKED PERFECT FOR ME EVERYTIME I NEEDED IT TO! VERY SATISFIED! THANK YOU! 😊

Had a phantom drain on my car battery. I would leave for work and it randomly wouldn't start. Rather than having to run around soliciting a jump, I can just pull this little beauty out. Less than 2 minutes later I'm rolling out under my own steam.Quick, portable, great size, super easy to use. Over all big win!The other day I was at a BBQ and my friends truck didn't want to start. I pull out my shiny new jump pack and BOOM! Problem solved. No need to rearrange vehicles, pull out tangled cables, figure out which side who's battery is on... (you know the drill). Like a pocket superpower!Didn't hit half-power and need to recharge until after 6 or 7 jumps. And I can recharge it with my car. Kind of like recycling.Very handy.The 'safety light' is a nice perk, as is the option of charging my other devices with it.Overall: great product at a good price!
