12V 24V Car Battery Charger Engine Starter, Up to 50A Automatic Battery Maintainer, 250 Cranking Amps, Auto Desulfator, Battery Repair, Winter Mode, for AGM STD Gel Deep Cycle Batteries

I’ve used this charger so far on a 200Ah battery, and it performed exceptionally well. I was able to cycle through the different current modes and confirm the charging amp matching up accurately. After testing, I set it to Auto mode, and it charged at around 15 amps until the battery neared full capacity, then automatically tapered down the current as expected. The menus are straightforward and easy to navigate with the buttons, and the build quality feels solid overall. The battery clamps are sturdy and well-made, and the cooling fan is surprisingly quiet when it kicks on. Overall, I’m very happy to replace my old charger with something that supports modern battery technology and works this well.

Worked great. Charged my battery in just a couple hours.

Replaced a decades old Craftsman [stolen]. only one could find had charger with booster. Works good for me. The cord areas on the sides is good for the leads but nowhere for the 110 cord, .

I had high hopes for this 12V/24V car battery charger and jump starter, but it was a huge disappointment. It claims to deliver 50A for starting a car, yet when I tried it on a vehicle with a battery voltage of 8.8V, it couldn’t even turn over the engine even after several minutes. Frustrated, I used a simple adapter with jumper cables connected to a Milwaukee battery, and the car started instantly. That’s right—a Milwaukee battery meant for a cordless drill outperformed this so-called “high-powered” charger. It looks sleek and flashy, like a Ferrari, but in reality, it performs like a moped—slow, weak, and utterly unreliable. Build quality looks nice, but the performance is extremely misleading. I wouldn’t recommend this product to anyone who actually needs a dependable charger or engine starter, even if it were offered for free.

Does what it is supposed to do.

It has strong horsepower and can store electricity for a long time, meeting my occasional needs when I'm away.

Works good so far. little on the noisy side.

I jumped my Volvo D13 with this charger

EXCELENTE ARTICULO. al ver otras calificaciones temí que me llegara un producto de calidad dudosa pero ya había comprado. Al recibirlo me llebo la sorpresa de ver que se trata de un equipo robusto, potente. De buen peso y construido con materiales de calidad y resistentes. Estoy evaluando su rendimiento conectado a un BMW X3 2024 HIBRIDO. Como estabilizador de voltaje para programar la ecu y diversos módulos y hasta el momento el articulo a demostrado ser capaz de cumplir con la misión. En conclusión. Lo recomiendo al 100% Bien. Superó mis expectativas en relación calidad y rendimiento
