Essential piece of equipment
Great product. I’ve since bought a second to go in my wife’s car. I have a 3 litre diesel Ute & this battery pack starts it up with ease & has done a few times. Have used it so many times I’ve lost count. We have 1 car, 1 Ute & 3 motorcycles at our house & every so often a battery is flat. Wouldn’t want to be without it now. Highly recommended.

Indispensable pour dépannage
Booster de qualité américaine. Fiable, indispensable dans l'auto. Construction robuste, sert de batterie de secours pour charger un smartphone et de lampe d'appoint pour éclairer en cas de panne.

Thoroughly impressed.
I purchased this in 2024 and have only just had an occasion to use it. I charged it in 2024, and it was still fully charged in 2026, even after sitting in the boot of the car all that time. I was amazed by how easy it was to use, how small it was, and how well it performed. It started a vehicle with a dead battery so easily. Gone are the days of needing a second car and jump leads. Just connect this, turn it on, flashing array of lights, then a white light and off you go. Seconds. Thoroughly impressed, enough to write a review.

Strong charger plenty of power for large v8s won’t leave you stranded
Excellent charger I have an s550 Mercedes with a V8 and battery dies after a few weeks without starting car . I have had other chargers that were suppose to be able to start big V8s and they struggled . This one you as soon as you connect and go to start fires right up . I use it pretty frequently because like I said I don’t use car very often once a month once or twice every 6 weeks and this charger so far hasn’t disappointed holds its charge well and even if you don’t recharge after a jump start still has plenty of power . I keep it in back of front seat and when I need it it works great won’t leave you stranded
