Review: Great battery maintainer - I am a service manager and have purchased several of these battery maintainers for my technicians to use while they perform lengthy software updates. The brand we work for (I won't call them out) has a similar product that they sell for 10 times this amount. We have been using these for well over 2 years now and they have held up and have not given us any issues with the exception of 1 unit which the company was happy to warranty out for us very quickly. I highly recommend these battery maintainers. Review: The simplicity is great! No adjustments. Just turn it on. - I use these for new module programming. I’ve never had a problem.

Just turn it on. ## Features - 🔋 The Power You Need – PowerMax can give some power to your RV, 12V Car Audio/ Stereo/ CV Radio, Boat trolling motors, and LED, and can provide some power to your house, lighting off-grid & solar backup. 12V Battery Charger has a power supply that you could connect to your car, then plug it in and play your car stereo without running the engine.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great battery maintainer *by K***Y on August 17, 2025* I am a service manager and have purchased several of these battery maintainers for my technicians to use while they perform lengthy software updates. The brand we work for (I won't call them out) has a similar product that they sell for 10 times this amount. We have been using these for well over 2 years now and they have held up and have not given us any issues with the exception of 1 unit which the company was happy to warranty out for us very quickly.

I’ve never had a problem. The simplicity is great! No adjustments. Just turn it on. ### ⭐⭐⭐⭐⭐ It’s simplicity is why i like it *by G***R on January 21, 2024* I love this for it’s simplicity. It’s either on, or it’s off. No settings to change. No time outs or other smart box features to worry about. I connect it to a vehicle, turn it on, and it’s already dialed in at a perfect voltage range for passthru programming of most cars. Literally set it and forget it. That peace of mind is invaluable for passthru programming. Runs between 13.6 and 14.4 vdc depending on the vehicle’s “ignition on” load. Cables are a bit long but I shortened mine to minimize voltage drop between the supply and the clamps. Cooling fan comes and goes as it should. I’ve ran mine on a program event for 3 hours without any issues. Would definitely buy this one again if i ever have to. ## 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.hr/products/28780492-powermax-pmbc-100-amp-12v-battery-charger-maintainer-flash-reprogrammer](https://www.desertcart.hr/products/28780492-powermax-pmbc-100-amp-12v-battery-charger-maintainer-flash-reprogrammer) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-22*
