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 item works great however the ground connection plastic part broke and can't seem to find out how to replace it.

A portable car battery jump starter is a lifesaver when you’re in a pinch. This compact and easy-to-carry device allows you to quickly jump-start your car without needing another vehicle. Many models also include extra features like built-in flashlights, USB ports for charging devices, and safety protections to prevent overcharging or short circuits. It’s incredibly convenient for emergencies, especially if you’re out on the road or in a remote area. Highly recommend a portable jump starter for anyone looking for peace of mind and extra security when driving!

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.

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.

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.

I don't like to leave negative reviews. I usually just leave a rating and forget about it - cos it's negative I guess. I ordered this after I regretfully left my GOOD one at our vacation home a few hundred miles away. I'd been hoping I wouldn't need it, of course - but this winter seems to have been hard on the car's battery and I didn't want to be scrambling for a ride on a cold morning before I'd replaced it. Sure enough, I needed a start soon after. I had FULLY charged this starter over the weekend, and put it in the trunk. THREE DAYS LATER - literally - I turned it on and the charge indicator had one BAR OUT.. meaning it had dropped from FULL charge to... well, 4 bars out of 5 lit. I attached it, thinking that should be enough - it's a little Subaru 4-cyl, not asking it to start a V8 or anything. .... click. click ... nope. I adjusted the cables, ensuring the best possible connection to the clean, dry battery terminals, made sure the unit was on [it doesn't have a "start" mode or anything else.. It is simply on or off... then it's multiple annoying flashing flashlight settings. So - IT IS ON. I plug it in again, see the voltages on the cable-attachment staging down to a nominal battery voltage of 12v. click. click. It will not turn over the starter. I leap inside the house and put it on the charger, pretty ticked off. Make a phone call that I'm running late - and give it an hour to "top off". It indicated a full charge, I went back out and after some fiddling _barely_ got it to turn over, albeit slowly and sluggishly.. wwwhhiir... whhiiirr... The car being in good overall condition, after 2 turns it started. OK. Maybe it was a fluke. Same thing happened a couple days later. Two days after charging it, t had drained a full "bar" and could not turn the engine. Bear in mind that I own another one [still at the vacation cabin unfortunately]. That one? After owning it for a YEAR ... and charging it app. bi-monthly, it will crank a V8 or V6 faithfully and reliably. It was a brand called UTRAI. I should have searched harder. I got a dud. The Li cells in this one are clearly beyond their best-by dates, they don't hold a charge and don't have sufficient "cranking amps" to reliably turn over my little Subaru 4-banger. It's a poorly-shaped doorstop at this point. Oh - and an $80 flashlight with quick-draining batteries. I'd keep searching. If I got a "dud" that's been in storage too long, how many more are in stock I wonder?

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!
