Quote from cdfbmw :
I bought one about 6 months ago and it has not started a car yet. I tried several times but just don't have the power to do it. It is an overpriced flashlight.
Was the car battery completely dead? If so did you enable boost mode?

Anyone know if this could be used as a battery for a 6.5 hp motor with a starter?

Quote from MisterOfMagma :
From the reviews:

"It does not Gonzalez charge

I tried sometimes but alwais displays on 78%

Can you help me?"

So a heads-up, if you need one that does a Gonzalez charge, this one won't work for you.
Gonzalez charge is not a term Google understands. If you meant forced charge for totally dead batteries, it does state that it has that.

If you meant Gonzalez as in "Speedy Gonzales" (fast), like fast charging for iphones or other phones/devices, or for recharging, it states that the 2 USB-A output ports are rated at 5V 2.1A, which is not very fast charging.

The USB-C port is input only for recharging this unit. Also not fast at 5V 2A, 9V 2A, or 12V 1.5A rates.

My best guess is you are saying the recharging of this unit is slow. If it never gets higher than 78%, it is defective or you are using a bad charging cord. Try another cord, and give it 24 hours is my advice. Then contact the company if alternative charging cords make no difference, or return it as defective.

Cable pack does not appear to have "boost mode" which is needed for a completely dead battery, at least don't see it in the pics or description. Can get them aftermarket from Amazon although I'm not sure if the 3rd party ones are rated for the full amperage of this unit if you plan on jumping a larger (6+ liter) engine.

These are complete garbage. I bought one a few months ago, it worked one time, then stopped charging. I bought another. Same exact thing happened after one use.
Current draw probably fried the electronics.

In a pinch rotate in one of your DeWalt or Milwaukee or other power tool battery and two heavy paper clips... You can modify this hack to make it more purty.

Doesn't this one look like a better deal for 27.99 after the 30% off coupon? I don't recognize either brand. https://a.co/d/f2IP0O6

Quote from Whitecrane :
Wouldn't rely on any of these to start your car. I have one, and as soon as it's configured to start a car, it gives an error message (blinking light pattern) and stops offering current. My understanding is none of them are built very well. The larger your car, the worse they will perform.
That's funny because AAA techs use lithium jump starters instead of jumping with their truck.

Gooloo makes quality jump starters. I've been using them for years and give them as presents too. Nobody has ever complained and always thank me when their car won't start.

How do you know if a device has "boost mode"?

Quote from conan1201 :
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
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
