Winter cold can be a real challenge for the batteries of cars, snowmobiles, and ATVs. In these situations, modern jump starters come to the rescue—compact and powerful boosters that can not only start your engine, but also charge a smartphone or tablet. Most models are designed for 12-volt systems, making them a universal solution for cars and small vehicles. However, lithium batteries have their own characteristics: they do not tolerate low temperatures well and gradually lose capacity over time. That’s why storing these devices inside your car is not recommended, and the battery’s lifespan directly depends on operating conditions.
This review features five of the most popular jump starters, all highly rated by users. For objectivity, we selected models with minimal risk of fake reviews, and ranked them by starting power. Each booster differs not only in technical specifications, but also in its range of additional features, allowing you to choose the best option for your needs.
Maximum power
The Hummer Power Bank HMRHX stands out for its high current output among available devices. This booster can handle even large diesel engines up to 7 liters and gasoline engines up to 8 liters. The starting current reaches 1,500 amps, while the device weighs just 415 grams. It features basic protection systems against incorrect connection, short circuits, and reverse current. Users praise its reliable cables and clamps, as well as its ease of use. However, it uses a lithium-ion battery, which affects its longevity and capacity—so it isn’t the most efficient power bank.
Next is the Carku jump starter Pro-60, designed for diesel engines up to 5 liters and gasoline engines up to 8 liters. It uses a 25 Ah lithium-polymer battery, making it an excellent choice for charging gadgets. The starting current is also 1,500 amps, and extra features include a powerful flashlight, USB Type-C ports, and QuickCharge. Protection against deep discharge and a broad array of connectors make this booster a versatile travel tool. According to owners, its build quality and kit aren’t quite on par with the leader, but its functionality is top-notch.
Quick Start
The Gigant GSD-25 stands out for its exceptionally high peak current—up to 2000 amps. This device features a 25 Ah lithium-polymer battery and supports fast charging via a QuickCharge port. The booster reliably starts diesel and gasoline engines and can also serve as a powerful power bank for smartphones, GPS navigators, and other devices. Users note its low defect rate and ease of use. Its compact size and well-designed protection system make the Gigant GSD-25 one of the most dependable options for winter travel.
The Berkut specialist JSL-15000 is designed for diesel engines up to 3 liters and gasoline engines up to 5 liters. It comes with a 13 Ah lithium-polymer battery and delivers 700 amps of starting current. The device offers the widest range of safety features, protecting against overheating, reverse polarity, short circuits, and other potential issues. Owners appreciate this booster for its ergonomic design and long-lasting battery, though the price is considered slightly high. As a power bank, the Berkut specialist JSL-15000 delivers average performance, but its capabilities are more than sufficient for engine starting.
Budget options
Quattro Elementi Nitro 7 790-304 is an ideal choice for owners of small gasoline cars. It delivers a starting current of 400 amps and has a battery capacity of 7.5 Ah. Weighing just 230 grams, the device is easy to use. Key advantages include its compact size, affordable price, and positive user reviews. One owner noted the booster managed to start a Lada Vesta engine six times in a row with the main battery removed, even in freezing conditions. The model features basic protection systems and a single USB Type-A port for charging gadgets.
Each of the devices presented has its own strengths and limitations. When choosing a booster, it’s important to consider not only the power and battery capacity but also the extra features that may be useful on the road. Modern jump starters are increasingly versatile, combining the functions of a car starter and a portable charger for electronic devices.
If you didn’t know, the Hummer brand is known not only for its vehicles, but also for a line of automotive accessories, including jump starters and power banks. Carku specializes in designing portable starters and charging solutions for devices, while Gigant and Berkut have long been recognized as reliable manufacturers of automotive accessories.
