Best Overall: TACKLIFE T8

Powerful and compact aren't words usually used to describe battery chargers. You typically need to choose between lots of power and an unwieldy design and small but underpowered. The TACKLIFE T8 offers the perfect balance of charging power and size. It restarts a dead 12v battery in seconds and can do so up to 30 times on a single charge.

The T8 has a long list of safety features, including spark-proof technology, reverse polarity protection, and a mistake-proof design. The T8 has an LCD screen that displays battery power and voltage, a built-in flashlight and compass, and battery clips with thick grips. You'll also get two USB ports on the charger's side for topping off smartphones, tablets, and other portables. The included directions could be better. They're riddled with errors and incorrect wording, but not so much that new drivers can't figure out what to do.

When you want a reliable portable car charger and power bank in one, you want the TACKLIFE T8. When turned off, the T8 holds a charge for up to one year. It's also small enough to fit in your glove box so that you can keep it at the ready year-round. This kit comes with the T8 charger, smart jumper cables, a wall charger, a USB cable, a cigarette lighter socket adapter, a protective case, and a user manual.

Best Value: NEXPOW G17

You'll keep a few extra bills in your wallet and go home with a reliable portable car battery charger when you invest in the NEXPOW G17. Unlike many other models, the G17 features Quick Charge 3.0 and has a Type-C port, which means you can do everything a little faster.

The G17 has 1500A plus 21800mAh capacity. It will jumpstart your vehicle, and it can fully charge laptops, smartphones, tablets, and other devices at record-breaking speeds. This small unit has a few safety features like its spark-proof design, reverse polarity protection, high temperature, and overload protection.

My only gripe with the G17 is that it requires frequent recharging. If you start a dead battery once or twice, you'll need to throw this on a wall outlet to juice it back up again. It's not as power-hungry when charging small devices via USB. This small power bank and car charger has an internal LED flashlight and SOS light for emergencies and comes with a carry case, jumper cables, and a Type-C cable.

Best in any weather: NOCO Boost Plus GB40

Out-of-life batteries fire up in seconds with the well-made NOCO Boost Plus GB40. This compact 1000A portable car starter will jump a car or truck up to 20 times before recharging. Unlike most car chargers, which require an AC adapter to recharge, the GB40 uses USB, so it can recharge via a cigarette lighter while you drive. And it takes only a few hours to charge fully. Nice!

The GB40 is a multifunction unit with a mistake-proof design. It has spark-proof tech and reverse polarity protection built-in. It also comes with a 100 lumen LED flashlight with seven light modes, including SOS, and it has one USB out port to top off your iPhone battery, Android device, tablet, and the like.

My favorite feature is the rugged, water-resistant build, rated at IP65. You can safely use this charger in the rain, snow, or hot or cold temperatures. I wish there were more than one USB port for charging external devices, but that's my only complaint. The GB40 is a safe, portable car battery charger with its own storage bag and charging cables.

Best Pro Level Power: DEWALT DXAEPS14

Dewalt Portable Battery Charger Next To Car Lifestyle

When you need a do-everything portable charger, go with the DEWALT DXAEPS14. It'll jumpstart your vehicle, run an alternator check, pump up your tires, and recharges two USB devices at once. How's that for handy? It's like having your mechanic in your trunk!

This DEWALT portable charger has a carry handle on top, so you can store it in the trunk or garage and grab it and go when needed. A brightly lit LED on the front gives an accurate readout of battery life, tire pressure, and more. This handy little model has 1600A and has no trouble starting up lifeless car or truck batteries.

You'd expect something this functional to be heavy-duty, and it is. It's also downright heavy. At 19 pounds, this can be a chore to pull out of the trunk for older or smaller users. Aside from that, if you want a tool that will cover all your bases, air your tires, and jumpstart your ride, this is it.

Best for Small Cars: Scosche PBJ700-1

Scosche Battery Charger Lifestyle

If you have a small car, there's no need to invest in a giant power supply. The SCOSCHE is a battery booster that works on vehicles up to eight cylinders, outputting 700 amps of power quickly. Its compact and lightweight build is rugged enough to last for years but sleek enough to store in the glove compartment or under the front seat.

There are many safety features with the SCOSCHE, including polarity, overheating, overcharging, and short circuit protection. Dual USB ports keep your portables in working order when you're on the road, and the built-in flashlight is handy. There's also a battery indicator level, so you know exactly when to top this charger up.

The SCOSCHE's shortcoming is with the weather. While it will hold up to rain and snow, this model will struggle to jumpstart any car if the temp dips below freezing. It'll boost a struggling battery but may or may not get a dead in the water battery back on the road. If that's not a concern for you, this is a rugged little charger that works well.

Not reliable in cold weather

It's not for winter, but this little charger works well in three seasons and two USB ports.

Bottom line

Magnetic mounts and cigarette lighter style chargers are some of the best iPhone car accessories on the market. Still, sometimes you need a multitasking tool that also works in emergencies. And this is where portable car battery chargers really shine. They'll charge up your phone and tablet, plus restart your car's ailing battery.

The TACKLIFE T8 is the best in show. It's a combo charger with 800A peak current, so it starts a dead car battery in seconds, plus a 18000mAh power bank with dual USB outputs for phones, tablets, laptops, and other portables.

The directions are subpar on this model, but the fool-proof design helps even newbies figure things out quickly. In standby mode, this bad boy holds a charge for up to a year. When in use, like when topping off your iPhone, you'll get a solid 4.5 hours of charging power. The T8 is small enough to fit in your glove box but still has enough juice to start a dead battery. It's perfect for cars, watercraft, ATVs and UTVs, and snowmobiles.
