Car Battery Jump Starter with Air Compressor,44.4Wh Battery Jump Box with Tire Inflator,Car Jump Booster with Smart Jumper Cables,LED Light Emergency Car Kits for Vehicles,Arrancador Ae Batería

I love these things! I was recently driving cross-country and had a car battery died, and a similar device was able to let me start my car enough times to make it in time to my destination (where I bought a new battery). So I have given that one away to a relative, and I will be using this one as my emergency backup now. I do think everyone should have one of these in their car if possible, especially if you have an older car. It would make a great gift.In terms of functionality for this device, it does seem to hold a charge fairly well, and it does have enough power to jump start a small car battery. The manual recommends charging at least once every 3 months. It also specifies that you shouldn't charge it for 30 minutes after using it to jump start a car, as it may need to cool down.It has a short-circuit protection mechanism, which I did not test. It's good to see at least some safety features on something like this. There's also an override button to bypass the short-circuit protection on the jumper cable connector.It charges somewhat slowly. The power output for the power bank portion is just a single USB A port, but it works fine. I think it's a great idea to have it function as a power bank at all, since my previous battery jump starter did not have this feature. It's not very impressive as a power bank, but it could be useful in an emergency.Overall, I'm happy to have it!

Met my expectations

I haven't had a chance to actually use it as a jump starter yet. But it seems to be well made. When I turned it on for the first time, the battery was at 95%. The led flashlight and light functions work properly. The USB port works and charged a device I have. The unit itself is heavy. It comes with a velvet pouch that has 2 compartments. One side is for the unit and the other is for the jumper cables. The close at the same time with a drawstring. It is compact enough to keep in your car. Just be sure to check the battery percentage once in a while so you won't be out of luck when you need it! It also comes with a USB-C charging cable. It is a good value.UPDATE 7-17-25: i recently used this to use my tablet when the battery on my tablet was low. After about 2-3 hours, the charge on this went from 99% to 22%. As a battery backup for your phone or tablet, it doesn't last very long. But if that doesn't concern you due to mainly wanting it for a jump starter, then disregard this update. But I thought it was an important update in case someone needed it in a pinch for the purpose of power for a tablet or iPad.

I bought this jump starter to keep in my car just in case, and it’s already saved me twice—once with my own dead battery and once helping a neighbor. It’s super easy to use, even if you’re not super car-savvy. The smart jumper cables are clearly labeled and make you feel confident you’re connecting everything safely. It’s compact enough to fit in my glove box, and the built-in LED light is a nice bonus for nighttime emergencies. The battery holds a charge for a long time, and it even has USB ports, so I’ve used it to charge my phone in a pinch too. Definitely one of those things you hope you don’t need often but are SO glad to have when you do.

Ive got an old 88 cherokee that has a parasitic draw from a previous owner playing silly buggers with the wiring. The battery goes dead more often than not on that vehicle, when i forget to plug it in. This jump starter does the trick of getting it going abd allowing me yo move the old adventure rig around whenever i need to. Highly recommend for high amp starting capacity! It's also great that it has a built in light so you can see what you're doing at night. And it even fits under the back seat of the jeep with the jack.

First off, I'm going to ding them for the size of the battery. For whatever reason, the manufactures seem to be having a fun time seeing if they can out-claim other manufactures on battery capacity, and it's getting completely out of control, sometimes with statements of battery sizes 10x more than is actually in the unit. Back on topic, this unit does indeed exaggerate, but it's not as flagrant as others. It claims 12000, where in reality it is around 7600, quite a bit off. Yes, there is a bit of loss that is always expected (5-15%), but this is nearly double. So I take a point of of every manufacture that refuses to put in realistic capacity numbers on their products.The second con is the charging time. This thing is SLOOOOW only accepting 2 amps on a USB-C port. That is not the worst, but close to the worst I've seen on a battery (on the picture, it's the left most USB-C using 11W). HOWEVER, while it's pretty silly to have such a low charge rate for anything made in the last few years, this really is not something you're charging every day, so I'll give it a pass.Third con, really should have USB-C output power as well. Again, kind of silly to have a USB-C plug and not have it configured for both input and output, that's just a waste.Now, for a battery bank, it does have a pretty slow typical 2.1A output (also confirmed by my meter), as is show on their screen. I did hook it up to a car that has a VERY weak battery, and it had no issues getting it going.So final conclusion, it does what it should (starts a car) but don't expect any bells and whistles out of this thing. It has just enough basics to work, and nothing else.

When my trusty old Chevy wouldn't start this morning, I followed the instructions to use this nifty little item. To my amazement, it started right up! No need to call a friend and hook up jumper cables to his car the old-fashioned way. Once it was charged, I just drove to my local auto parts store where they checked and replaced the battery as I waited. This was really really easy and I highly recommend it!
