There are all sorts ofportable laptop chargers designed for smartphones, tablets, laptops, and mobile game systems, but the Halo Bolt one-ups them in one fundamental respect: it can also jump-start your car. This heavy brick of a portable charger proves to be a handy tool, especially in the car—whether for emergencies or when you need to top up a device while you’re away from home.

Granted, it doesn’t pack as much power as some dedicated laptop chargers, which may be a better option for that need. Still, the added versatility gives the Halo Bolt a unique edge in the market. I tested the Halo Bolt for a week with multiple devices, including laptops and smartphones.

Design: The shiny brick

While certainly portable, the Halo Bolt isn’t designed to be pocket-friendly. This big brick of a battery pack comes in at 7.2 x 1.6 x 3.8 inches (HWD) with a weight of more than 1.5 pounds. Smaller, cheaper battery packs are available for smartphones, but this beast is made for heavier-duty needs and is designed accordingly.

It’s made of mostly thick black plastic outside, including a glossy brushed silver top layer with an imprinted Halo logo. The front face is where most of the ports sit, including two USB-A ports (5V/2.4A), a DC input for the charging adapter, and jump-start inputs hidden behind a small door. The right side, meanwhile, has the 115V AC/65W max AC power plug input for laptop chargers and other plug-in devices.

Smaller, cheaper battery packs are available for smartphones, but this beast is made for heavier-duty needs and is designed accordingly.

Each set of inputs has a power button to activate the ports, and you can use the AC input and USB ports simultaneously, but the Jump Starter can only function independently. Meanwhile, the left side of the device has a bright built-in LED flashlight with a power button, giving you another handy tool during car emergencies.

The Halo Bolt also comes with an array of accessories, including a wall charging adapter, a car charging adapter, jumper cables, a USB-to-micro USB cable, and a cinching pouch for quick storage of all the above. All of the cables and accessories are a welcome bonus.

Setup Process: Load it up

You’ll need to charge the brick to total capacity before using it, and the four green battery lights on the right side of the front face indicate how much capacity is currently left. The battery is fully charged when all four are illuminated when pressing any of the power buttons. Otherwise, for the AC and USB ports, the Halo Bolt is a plug-and-play charger.

The whole process for jump-starting a car is detailed in the included instructions. The Halo Bolt has built-in safety features that ensure you have correctly aligned the jumper cables before starting the connected car, boat, lawnmower, or other vehicles.

Charging Speed and Battery: Not so long-lasting

The Halo Bolt has 58,830mWh of battery power within, and the official description suggests that it can provide up to several hours of additional usage for a MacBook Pro oriPad Air . In my testing, the results didn’t quite match those targets.

Plugging in amid-2019 MacBook Pro (13-inch) with its own AC adapter, the Halo Bolt charged it quickly but ran out of juice before the battery could fully recharge. It went from 0 percent to 88 percent in 1 hour and 30 minutes, at a maximum recorded charging rate of 58.29W (20.1V/1.9A).

In a separate test, I played a locally-downloaded movie on loop at 100 percent brightness on the laptop, with the Halo Bolt plugged in to sustain the laptop’s fully-charged battery. The Halo Bolt provided power to the computer for 5 hours, 14 minutes before running out of battery, but that’s a fair bit less than the Mophie Powerstation AC (6 hours, 22 minutes) and ZMI PowerPort 20000 (8 hours, 4 minutes) in the same test.

Plugging in a mid-2019 MacBook Pro (13-inch) with its own AC adapter, the Halo Bolt charged it quickly but ran out of juice before the battery could fully recharge.

Not having a USB-C Power Delivery port on the Halo Bolt is disappointing, as many modern devices rely on the standard for speedy charging. You’ll need to bring your own AC adapters to plug into the AC port to get maximum speeds.

For example, charging aSamsung Galaxy S10 smartphone using one of the Halo Bolt’s USB-A ports took 2 hours and 56 minutes to complete at a paltry 5.19W (4.76V x 1.09A), starting from 0 percent. However, when I repeated the test using Samsung’s charger via the AC port, it finished in 1 hour and 34 minutes thanks to fast charging—nearly half the total time.

Price: It’s priced right

For a jack-of-all-trades power brick that can jump-start your car and charge its battery, serve as a bright flashlight for roadside emergencies, and charge a wide array of portable devices, the $100 price seen on Amazon looks pretty reasonable. However, given that it couldn’t charge my laptop to total capacity and lacks a USB-C port, handier, higher-capacity charging bricks are available specifically for laptop and smartphone charging needs.

Halo Bolt ACDC 58830 vs. ZMI PowerPack 20000

Here’s a prime example. TheZMI PowerPack 20000 (see onAmazon ) doesn’t have an AC port. However, it’s pocket-friendly, packs a lot of capacity (20,000mAh), and can quickly recharge laptops with its included USB-C port. It also has two USB-A ports and sufficient juice to recharge the same MacBook Pro from empty. Best of all, it only costs $70.

But that smaller, cheaper power brick is only meant for portable devices such as laptops, smartphones, tablets, and handheld game systems. It has no jump-start capabilities nor an AC port to accommodate a wider array of devices.

Final Verdict

Final Verdict: A convenient backup battery and jump starter.

The Halo Bolt isn’t the best option for charging laptops, but it is a solid all-around device for providing backup power to a broader array of gadgets, not to mention jump-starting a car. This versatile device is smart to have around if you drive a car and are frequently mobile with your portable gadgets. I wouldn’t bring it with me on vacation, but it could prove useful before long as a backup device to keep handy.
