How We Decided
All of our picks for the best car battery charger were chosen based on their overall charging performance, as well as their safety and quality of life features. The standard amperage output of car battery chargers is about 2A, while jump starters commonly peak at 800A, so we picked the ones that were close to those numbers (with the exception of the Schumacher S1280 Rapid Charger).
We prioritized items that are equipped with standard reverse polarity safety measures to prevent any user-made errors. We also gave bonus points to products that came with extra features such as auto-switching or auto-cutoffs to prevent overcharging. All of these chargers are compatible with the most commonly used battery types in the country for the sake of convenience.
The Most Important Features to Consider
The ampere (A) output of a charger determines how fast it can charge a battery; the higher the number, the faster the charge rate. It’s important to note that higher amperage rates may damage batteries or worse, start fires.
- Safety Features
Batteries are prone to damage because of the complex mix of chemicals inside them, which is why a charger should always have some form of safety measure. This can prevent a battery from sustaining irreparable damage or from causing harm to you or anyone else.
- USB or Smart Device Charging
Power bank-style car chargers typically come with USB charging ports for you to charge them with. These ports can also be used to power up mobile devices like laptops and smartphones to keep them topped off in case of an emergency.
- What’s the difference between a car battery charger and a jump starter?
The difference lies in three factors: charging speed, power, and size. Jump starters are used more for emergency purposes while batteries are for maintenance. Jump starters have stronger electrical currents than chargers. This means they can give your battery a small yet quick charge to get you out of a pinch, but ultimately, you’ll still need to charge your car in the end. On the other hand, chargers trickle power into your battery. It will take much longer before you can start your car again, but you’ll be able to fully charge your battery, unlike jump starters.
- Can jump starters charge your battery?
Jump starters are only meant to supply your battery with enough power to start a vehicle.
- What is a maintainer?
As its name implies, a car battery maintainer is designed to maintain the current level of charge that your battery has. Maintainers slowly trickle small amounts of energy to your battery to sustain them over long periods of time. This will keep your battery from self-discharging. And since the amount of electricity being supplied is so small, your battery will also be safe from overcharging.
