It is rated for 100 amps. You need to know what your load is so you don't overload it. I have a real concern for your ears if you need all of its power! **Q: I saw a previous question that was answered very vaguely: I see the title saying it's rated at 100 amps but the pictures say 75amp, which is it??** A: I bought a 100A unit, received a 100A unit. Picture showed 75A. **Q: can it start a car with a dead battery?** A: Yes AND no. It is not a jump starter but can re-charge a battery over time from being very weak. More info would be needed based on your situation. **Q: Can this be used to charge a battery overnight or will it overcharge/fry a battery?** A: You can charge a battery with this but the usage is more for a battery maintainer in programming in automotive vehicles. ## Frequently Bought Together - PowerMax PMBC 100 Amp 12V Battery Charger/Maintainer, Flash Reprogrammer & Adjustable Power Supply w/ 15ft Cables, Voltage Display & Mounting Brackets for RV, 12V Car Audio, Boat Motors & LED + House - Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter , Blue - Schumacher Electric DSR ProSeries Car Battery Jump Starter - 2200 Peak Amp 12V Car Starter, Jump Box & Portable Power Station - Digital Display, Heavy-Duty Clamps - DSR165 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/28780492-powermax-pmbc-100-amp-12v-battery-charger-maintainer-flash-reprogrammer](https://www.desertcart.ro/products/28780492-powermax-pmbc-100-amp-12v-battery-charger-maintainer-flash-reprogrammer) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-08*
