Will it start a V8 truck or a diesel?

It is rated for most gas engines up to large V8s and many light diesels. Very large diesel engines may need a higher-capacity booster.

How do I recharge it?

It charges through a DC adapter, either from a wall outlet with the included adapter or from a car's 12V socket. A full charge takes several hours.

How often should I charge it?

Top it up every three to six months, or after any use, so it is ready when you need it.

What comes in the box?

The jump starter, smart jumper clamps, a DC charging adapter and a carry case. Check the listing for the exact bundle.

Is $59.99 a good price?

At $59.99 at Best Buy as of November 7, 2026, it is near the bottom of its recent range and cheaper than most 4,000A-class jump packs.

Can it charge my phone?

Yes. The 27,800mAh battery has USB output for phones and tablets, plus a built-in flashlight.

Our take on the AVAPOW 4000A Peak 27800mAh Portable Car Jump Starter

The AVAPOW 4000A is a pocket-sized lithium jump pack rated at 4,000 peak amps and 27,800mAh, meant to start cars, trucks and SUVs with dead batteries without another vehicle. It doubles as a USB power bank and a flashlight, and it recharges over DC. At $59.99 at Best Buy as of November 7, 2026, it sits at the low end of what this model has sold for recently, and only two stores list it new.

Cons

Peak amps are a marketing figure; real cranking output is lower

No USB-C fast charging on this model
Clamps and cables are short, which can make reaching battery terminals awkward
Must be topped up every few months or it loses charge
