Great item to have in your car for back up. Fast charge and easy to use. Compact does not take up space. A lot cheaper then other brands and works great. No more cables. I start up everyone's car that's dead. Hook up start and done. Must have. Read more

Worked as described

LuisFebruary 5, 2025✓ Verified purchase

ordered this as a “just in case“ and I ended up using it the same day I got it. Hooked it up to my coworkers v8 truck and it started right up. It’s feels sturdy and is a good size to keep in the glove compartment. Read more

This is the one

RodneyJanuary 18, 2025✓ Verified purchase

i wanted a car jumper that served multiple purposes, occasionally jumping a dead battery, primarily charging my computer, but most importantly, fast recharging. after a week of research, i happily settled on this device. Takes about an hour to fully recharge, while also taking about an hour to fully recharge a dead phone or computer. best part is the 150w car charger that it comes with! only negative is there’s no case for it. 10/10 would recommend.

EladfitzOctober 19, 2024✓ Verified purchase

I have a Chevy Suburban, don't drive sometimes for up to a week. twice now I've left things pugged in and ran the battery flat dead (had to unlock with key) This thing started it instantly both times. Also good to hook to small engines electric starter instead of buying batteries, works like a charm Read more

WON’T CHARGE? Don’t return. READ THIS FIRST!

HarryJuly 15, 2024✓ Verified purchase

This device will ONLY charge with a POWER MODULE that outputs to the provided USB-C double ended cable. See my photos. Mine charged from 75% to 100% in less than an hour. There’s a super expensive YesPer 200 watt power supply, but it will drain your wallet. This 20 watt CA-43T off brand module which I have for iPhone works fine. Read more

USES A NON STANDARD CONNECTOR FOR CABLE

TimmyDecember 3, 2023✓ Verified purchase

This will not be a problem for most user unless they need to replace cable or add an adapter. Almost all other jump packs use an EC 5 or have adapters available to be able to convert their plug to EC5. Cables are on the short side and I wanted to be able to use short EC 5 extension and I have SAE connector wired directly to my batteries to charge them and wanted to be able to use an EC 5 to SAE to jump the battery since it is the floor of my trunk. I am not sure what type is used on the Fast Max but it is not compatible with EC 5 or EC 3 and I can not find any adapter that fit. The jump pack seem to work well and charges devices and accepts recharging and holds it charge Read more
