Best Battery Chargers of 2025

"I don't drive much since retiring, and my car was having battery issues. After considering a $200 battery replacement, I found the NOCO Genius 1. It's super simple to use and effectively maintains my battery. It's a great investment that has saved me from the hassle of a dead vehicle after vacations!"

"I own a truck that often sits idle, and my battery frequently dies. After using this charger, I was quite impressed with its performance. It took a day and a half to fully charge my battery. Unlike my old chargers, this one is safe for prolonged use and seems very well-made. The only downside is that the manual could be more informative."

"Según todo lo leído, es de los mejores. En oferta, vale lo mismo que en USA. Apenas lo estoy probando, y lo único 'raro' es que el manual no explica bien cómo se usa el modo de recuperación. Pero, por lo demás, como mantenedor de carga, ¡PERFECTO!"

"I had a dead battery on our home generator and used this charger for 24 hours. Now, the battery is fully charged, and the generator started without issues. The instructions were straightforward, although I needed a magnifying glass to read them. I’ll test the trickle charging feature and update if there are any problems, but so far, it works as advertised."

"I got this charger for my generator battery that stopped working and also needed a trickle charger for my truck. It automatically detects the battery status, which was impressive. It charged the battery but dropped 9 amps overnight on my son's friend's car, showing that it works well, even if slowly. My only complaints are the short power cord and gator clamp cables."

"After my car battery died a month after the warranty expired, I ordered this charger based on great reviews. It was delivered in 12 hours and was easy to use. The diagnostics told me what was wrong with the battery, and six hours later, I was back on the road. Excellent product!"

"I bought this to replace an old charger. The Noco Genius 10 is compact and lightweight, making it easy to use. I quickly charged my BMW's battery in just two hours. The only downsides were the short power cable and slightly tricky clips to attach."

"After doing some research, I ordered the NOCO Genius 10 to revive my dead car battery. I connected it and let it charge overnight. The next morning, the green light signaled a full charge. My car started effortlessly — it works as promised!"

"Over the past four years, I've been able to recharge multiple batteries with this unit. The Repair Mode even improved my oldest deep cycle battery significantly. It’s definitely paid for itself with its excellent performance."

"I wish it came with a hard case, but it works little miracles like jumping two cars on one charge. Compact and easy to use; I didn’t even need to read a manual!"

"The NOCO Boost Plus GB40 is one of my best purchases. Peace of mind for my motorcycle; I even got my family to buy one after using it successfully. The safety features are impressive!"

"I ordered this NOCO Boost Plus and it arrived without a charging cable. But, customer support was fantastic! They sent me the cable within two days. Amazing product and service!"

"I found this charger to be incredibly effective. It worked right out of the box, charging my car's almost dead battery to 80% in just a couple of hours. It's straightforward to use!"

"This charger has been a game-changer for my sister's car with a faulty alternator. The pulse repair feature is impressive, and the display shows the charging progress clearly. It's compact and easy to move around."

"As someone who keeps my motorcycle plugged in during winter, I appreciate this charger’s performance and features. While it’s a bit more complicated than I’d prefer, it keeps my battery health at 100% and does its job well."

"I really like this charger for jump-starting my car, but I wish it had an AGM or Gel battery selection."

"As someone in the automotive business, I find this charger reliable and effective. It hasn't let me down yet, and I definitely recommend it."

"I was able to restore a battery that wouldn’t hold a charge. It’s incredibly simple to use, and I appreciate the affordable price for such a powerful unit!"

"When I first received my charger, I connected it to my diesel truck, but the cold weather had drained the batteries. However, the unit immediately recognized the 24V series batteries and charged them up to 100% without any issues. I particularly appreciate the LED charge level indicator, which removes any guesswork about charging. It's lightweight and seems sturdy. I recommend it for its ease of use and portability."

"I wasn't initially impressed with my charger because it felt so light, but it has proven to be a great performer on every battery I've used it with. The repair feature is particularly useful and works effectively, while the charging speed is acceptable. I do wish I had bought the 25 amp model instead of the 20 amp, but I'm happy with my purchase so far. Thank you!"

"I had high expectations for the YONHAN Battery Charger, but it turned out to be quite troublesome. It often gets stuck in a ‘charging’ state without actually charging. The battery repair function didn't produce any improvement, and the winter mode seemed more like a gimmick. The charger feels cheaply built and the instructions are unclear, making it hard to use the features properly. Overall, it has led to more frustration than satisfaction, and I wouldn’t recommend it."

"I was blown away by the NOCO GENIUS5! It's incredibly versatile, charging both standard and LiFePO4 batteries effortlessly. The interface is straightforward, making it easy to select modes. The charging is fast and efficient, and the smart features give me confidence that my batteries are well cared for. I feel safe knowing it has built-in safety features to prevent overcharging. I highly recommend this charger!"

"After leaving my lights on, I found myself in need of a jump. I bought the Noco Genius5 after a recommendation and it worked wonders! I set it to AGM mode and waited for the solid green light. My truck started up sounding better than ever! After hooking it back up, I found that all the codes were gone. This device is absolutely legit, and I would give it a 10/10 recommendation!"

"I’ve used this on various 6V and 12V batteries. The instructions were minimal, but there’s a helpful video link. The system is intuitive, and I found it easy to navigate the 12V options. It charged as expected, and I highly recommend it for reliable performance."

"I bought this charger after my old one failed. It charges completely dead batteries, which is essential for me. Easy to use with a clear display showing charging current and voltage. I love the automatic shut-off feature when the battery is fully charged. It can even repair sulfated batteries, which is a plus for older batteries."

"Just got the charger a few days ago. It works as advertised, and while the fan is audible, it's not bothersome in my shop. The display is great, and the leads are solid, but I wish the lead storage hooks were larger. One downside was the instructions; they didn’t clarify settings for deep-cycle batteries, which was a bit confusing."

"I used the charger on my wife's car battery. It worked well and even helped jump-start her car. Just keep in mind, it needs to be plugged in to work. It’s great for maintaining battery health too!"

"I love that it's American made and aligns with my resolution to support local products."

"This charger fits perfectly with my other tools in the shop!"

"I had issues with the machine; it simply does not work. I attempted to return it, but the return window had closed."
