Bought one recently and had to return due to charging issue. It kept showing error when I charged it for the first time. I tried 3 different chargers and cables. It could be my luck but I didn't want to take another chance.

Bought one of this type of cheap lithium chargers, different brand YABER. It did work for a couple of jump starts on a sedan but has stopped holding a charge properly (will not fully charge and the battery is leaking charge, 4 lights to 3 lights overnight) and no longer provides right current/voltage to jump. About 18 months old. I know this isn't the same brand but a lot of these are made with the same general design and technology, FYI.

Just FYI if you're not experienced with these… if you leave them in your car almost year round they tend to last 2-3 years at most. Buying for less than 40 dollars is what I tend to do. They're basically throw away every 2-3 years
Maybe theyr diff quality? I've had one in my car for over 5 years at this point and it's still holding a charge.

Have not tested a jump yet but charged to to 100% just fine. Flashlight is pretty good flood light. Overall it's really beefy, looks well made. Storage case is great as well. I bought a 2nd one just now.

I've had this for about 6 months and it has worked great. I had to use it a lot, until I had time to replace my alternator. I've never had an issue with this. People need to realize that it not working for them doesn't mean it doesn't work. If it's not working, it's more likely that it's user error or a bigger problem with your battery and/or car, like your alternator. People who don't know anything about cars are very frustrating.

Pulled the trigger after reading the reviews. Nice to have under the car seat just in case. Sure beats having to call somebody to jump start the battery.

But does it actually jump a vehicle? I have a couple (Stanley brand) and after a few years, one "holds a charge" and the other one will die after a few days of charging. Neither one of them will jump start a vehicle now, not even a riding mower.

I never leave mine in the car, unless we're on a road trip. Always store indoors at room temp, for best battery life.

ESPECIALLY in the summer, as heat kills these.
Believe the cold kills them just as badly too.

Yes. Jumps my 5.7 litre engine so easily

How do you know if a device has "boost mode"?
There's usually a button on the module that plugs into the pack.

U don't leave these in your car, dangerous. you buy a super capacitor jump starter if you want to leave in since they don't have a battery and rely on residual battery power to charge when needed
Then what's the point of buying these? They need to be in the car when I need them and I don't know when that would be.

I think this is a scam item. They know you won't use it right away or ever. I bought one of these to replace a $200 one. I used it as a battery pack for my phone in a hospital and it worked ok. Drained very fast compared to name brand battery. I tried to jump my car with a weak battery. Didn't do anything after one attempt to start and the screen went dead

I looked it up in my Amazon orders. I bought it in June of 2020. Brand is tackife. 18000mah. It doesn't look like you can buy it anymore. But I seriously doubt it's any different from any of this other Chinese knockoff crap. This is definitely a Chinese device. edit: looks like I paid $69.99. so I probably got ripped off lol

according to Rufus:

This jump starter has a force start function in the jumper clamps that delivers powerful performance to bring a vehicle back to life even if the vehicle has a completely dead battery at 0V.
