In addition to this, there's a lot of marketing trickery as well. I would compare only the watt hours between models. Most of these, if not all, use 4-cell pouches wired in series or (4) 3.7v in series for 14.8v total output (also known as a 4S pack) and they add up the mah of each cell to advertise their total mah. So depending on the voltage of the pack the mah rating can differ greatly depending on what method they use, for example (4) 2,000mah cells in series would make a 2,000mah 14.8v pack but they'll advertise it as an 8,000mah using the cells individual capacities added together which is misleading.

So your 32,000mah pack example would be the value rated at 3.7v, and therefore really be 8,000mah at 14.8v but 32,000mah sounds a lot better!

Alas, you are indeed correct, an 8,000mah 14.8v jump starter will deliver more power than the 2,000mah 14.8v version. It will also withstand a higher current draw more safely and therefore not puff up as easily.

I wouldn't expect it to put out much watts/amps.

I would actually prefer not to have lipo pouches as they always end up puffing up and becoming useless in short order.

That said, I am not aware of any of these that use cylindrical cells likely due to the higher cost of high current/capacity cells. Lipo pouches in comparison are cheap.

There a video review in the Amazon app. The guy takes it apart to show the battery pack. Says it only charges external devices via USB for 5 minutes then turns off. Cables are thinner than noco and the clamps are bulkier. With all that said it's still not a bad deal as it's half the price of the noco

Name jokes aside, these are nice jumpers. I own one that has a built in tire inflator. I wouldn't hesitate to purchase at this price.

I'm getting the MagnetoStorm version, so it will work wireless.

Looking at the quality of this, and the gauge of the wires, I wouldn't trust this anywhere over 1ka, never less 2000 amp. But for a regular car that pulls 400-700? Cheap insurance, if you remember to keep it charged

Honest question here: this deal or something like this guy https://www.amazon.com/dp/B0D2HDJ2TM <— looks like $10 coupon brings to $60, so +$20 for tire inflation, but not apples-to-apples on jumping (worse) and no usb charging

I do want a second jumper for another car.

Do I look for a Swiss Army knife that jumps + tire inflation + USB charge & flashlight? Or do I go for solid jumper separately?

Thoughts?
