Cars come in all shapes, sizes, and engine sizes, and thankfully, the HULKMAN works with almost all of them. You can drive a small compact car with a 4-cylinder engine or a big Ford F-250 diesel truck, and this can start them all.

Thanks to a large 20,000 mAh internal battery capable of 2,000 amps of cranking power, this jump starter works with almost any gas vehicle up to an 8.5L engine or all 12-volt diesel engines up to 6.0L.

The first thing I noticed was the build quality—everything from the box, packaging, and accessories to the overall jump starter is exceptionally well made. The battery is super rugged, features an IP65 dust and water resistance rating, and flaps cover all the ports. Throw it in the trunk, or have it sitting in the garage ready to go whenever it’s needed.

Everything about this jump starter is easy and fast. It recharges incredibly quickly and faster than most on the market, takes less than a minute to jump-start a vehicle, and you’re all done. My only real complaint about this portable starter is the length of the jumper cables. They’re only 15.5-inches long, which could be too short depending on your car battery location.

The best part about the HULKMAN Alpha 85 is its straightforward use. Even if you don’t know how to jump-start a car or change a tire, it’s easy. And while I’d still recommend reading the manual to be safe, it’s pretty foolproof.

You plug the jumper cable end port to the Alpha 85, connect the alligator clamps to your car battery on the positive and negative terminals, and wait for the screen to say “Ready” with a big green logo. Then, start your car. If the jump starter battery is too low or you don’t attach the jumper cables correctly, it’ll show you an error code on the large, easy-to-read display.

I tested it out on my dad’s old Chevy El Camino SS that sat in his garage for too long and was completely dead. That thing has a V8 350 Quadra Jet engine and a big old battery to keep it roaring. The few lights on the old dash lit up in 4-5 seconds, and within 10 seconds, I turned the key. Surprisingly, it fired right up on the first try. The car started with zero trouble as if the battery was charged and ready to go.

Jump starting that old car took the Alpha 85 from 99% battery to 94% battery. Then, after a weekend of camping and off-roading in my Toyota Tacoma, I left some lights on overnight, and, as expected, the battery was dead the following day.

I went outside, popped the hood, hooked up the HULKMAN Alpha 85, waited for the green “ready” light, and she started up almost instantly. It’s that simple. With this second boost, the HULKMAN Alpha 85 battery went from 94% to 90%. Judging by those numbers, it’s safe to say the advertised “up to 20 jump starts on a single charge” is reasonably accurate.

My truck was up and running in under a minute, and I didn’t need to dig out jumper cables, call anyone, or get a second car close enough to give me a jump. The Alpha 85 did it for me, and it couldn’t be easier. Remember that HULKMAN says to remove the jump starter from your car battery within 30 seconds of starting the vehicle to be safe and prevent damage or unnecessary drain.

The screen has a large 3.3-inch display to easily show you the remaining battery capacity or spit out any error codes if something goes wrong. Thankfully, I couldn’t test out any of those situations, as it worked as expected, and I started both vehicles without a hiccup. If you hook it up and get an error instead of the ready light, refer to the user manual for help.

And if you happen to use it enough that the jump starter runs out of battery, or it sits in your garage longer than the 18-month shelf life of the internal battery, you can recharge it from 0-20% in just five minutes. That’ll give you enough juice to jump-start any vehicle it can handle.

These portable jump starters can be charged with the included 65W fast wall-plug adapter, cigarette lighter-style 12-volt male adapter, or a USB port. That means you could theoretically jump-start your vehicle, then recharge the HULKMAN from the car as you drive, so you’ll always be ready to go.

As we said earlier, this isn’t just a device to jump-start your car. It’ll also charge your smartphone if you accidentally run out of battery, double as a flashlight, or even flash red lights if you’re stuck on the side of the road. On the bottom (or left side), pull down the flap, and you’ll find a high-speed USB-C power delivery port, a full USB-A port, and the 12V out for the cigarette lighter adapter.

It uses the USB-C port to fast charge the device itself, which reduces the need for extra ports. With a 20,000 mAh battery inside, you could technically recharge the latest Samsung Galaxy or iPhone nearly four times from 0-100%, so it’s pretty useful.

However, my favorite aspect is the built-in flashlight. If you’re stuck on the side of the road at night changing a tire or out camping, lights always come in handy.

There’s a power button on the right side, with a flashlight button under it. Push and hold, and the LED lights will fire up with five different modes: low, high, flashing white, SOS, and red flashing lights.

Most portable jump starters have lights, but these are nice and bright, durable, and have several different modes. I appreciate the ability to turn on a light to see in the dark, ensuring the jumper cables are on the right battery terminal.

Should you buy the HULKMAN Alpha 85? Absolutely! In fact, I would highly recommend carrying one in every vehicle you own. No one plans for a dead car battery, but it’s something that happens to the best of us. And unfortunately, it usually occurs on a day you’re already running late for work. So, be prepared for that situation ahead of time by getting one of these.

Being able to instantly pull out the HULKMAN and boost the battery in under a minute or two makes this perfect. And with a long shelf life and the ability to start most vehicles, you can store it in your car and lend a hand to others on the road if the situation presents itself.

It’s small, portable, and easy to use, so there’s no reason not to have one in the case of an emergency. It’s not just for jump-starting a dead car battery, either. Having one device that can start my truck, charge my gadgets, or double as a flashlight makes this handy little gadget a game-changer.
