The Lifmocer GS400 car battery starter delivers impressive 4000A peak current, easily jump-starting my car and even larger vehicles. Portable and sturdy, it’s become my go-to emergency tool. The included safety features and USB charging ports add great value. Highly recommended!
I replaced my old 2000A jump starter with the GS400, and the improvement is clear. It starts my SUV instantly, even on cold mornings, and the build feels sturdier. The extra power and added features make it worth the switch.
I had a quick question about the GS400 battery jump starter before buying and contacted Lifmocer’s support — they responded the same day with a clear and friendly explanation. That gave me confidence to order. The product arrived on time, and the jump starter looks powerful and well-made. Haven’t had to use it yet, but the buying experience was smooth thanks to their helpful team.
I was stuck late at night with a completely dead battery and no one around. The Lifmocer GS400 saved me—started my truck instantly. Super easy to use, even in the dark, thanks to the built-in light. I’ve tried a few portable jump starters before, but this one is by far the most powerful and compact. Definitely keeping it in my car year-round.
I got the Lifmocer GS400 battery jump starter mainly for emergency starts, but I was surprised how well it works as a portable power bank too. Charged my phone and tablet while camping, and still had enough juice to start my 5.3L V8 truck. Solid build, clear screen, and the 4000A rating really delivers.
