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. ## Frequently Bought Together - AZZUNOX Professional 50-Amp Battery Charger, 12V and 24V Automotive Charger, 250 Cranking Amps, Trickle Charger Smart Battery Maintainer, Ideal for Motorcycle Cars Trucks Marine Batteries etc - NOCO GENIUS2D: 2A 12V Smart Onboard Battery Charger - Direct-Mount Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid Batteries - NOCO GC004 X-Connect 10-Foot Extension Cable Accessory Genius Smart Battery Chargers --- ## 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.co.za/products/733013958-12v-24v-car-battery-charger-and-engine-starter-up-to](https://www.desertcart.co.za/products/733013958-12v-24v-car-battery-charger-and-engine-starter-up-to) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-10*
