Review: the Halo Bolt Air jumpstarts dead car batteries and fills flat tires

One of the most exciting developments in the vehicle preparation market over the past few years has been the rise of modern battery technology, which has led to the creation of a new category of personal, portable power solutions. These devices are designed not just for jump-starting a dead car battery but also for tackling other power-related vehicle issues on the go.
I've always been a fan of investing in high-quality tools that do one thing exceptionally well. Many "multi-tool" survival products often end up being underperformers because they try to do too much. That’s why I was initially skeptical when my wife gave me a Halo Bolt Air for Christmas. But after using it, I quickly realized how valuable it could be — especially in tight spaces or when you need something quick and reliable.
The Halo Bolt Air isn’t the top-performing device in its class, but it offers a compact and functional solution for people with limited storage in their vehicles. I remember a weekend trip to Atlanta where I was stuck in the back of a Volkswagen Jetta, or our Honda Pilot, which is already cramped with three kids in the second row. In those situations, having a small, efficient tool like this makes all the difference.
**Summary:**
- **Price:** Around $130 (often on sale for $100), weighs 2.53 pounds, dimensions in the included bag: 12†x 6†x 2â€.
- **Functionality:** All features work as intended. I’ve used it to jump-start a truck and inflate a tire successfully.
- **Air Compressor:** It inflates tires quickly, but it drains the battery at a rate of about 3% per 5 PSI. The built-in pressure gauge is usually off by around 5 PSI.
- **Jumper Cables:** The 8-inch cables are shorter than ideal, but that’s common in this category.
- **USB Ports:** Two 5V 2.4A USB-A ports are great for charging phones, but not suitable as a full replacement for a dedicated power bank.
- **Floodlight:** A useful backup light, best used as a warning beacon, not a substitute for a proper flashlight.
**Jump Starting with the Halo Bolt Air**
Battery-powered jump starters have revolutionized roadside emergencies, much like Fix-A-Flat did for flat tires. Before these devices, you had to rely on someone else's car for a jump start, which wasn’t always easy or safe. Now, with a jump starter like the Halo Bolt Air, you can get your car running without any hassle.
I recently tested the Halo Bolt Air when the temperature dropped to single digits, and my Dodge Ram 1500 wouldn’t start. I decided to use the Halo Bolt Air instead of my usual jump starter. The unit comes with a drawstring bag that includes the main unit and accessories, such as jumper clamps. It even has simple instructions for both the jump starter and air compressor functions.
The jumper cables are short (about 8 inches), so positioning the unit near the battery took some effort. Once connected, the Halo Bolt Air worked perfectly — the truck started right away, and the battery level remained at 100%.
**Inflating Tires with the Halo Bolt Air**
While the jump-start feature works well, the air compressor leaves room for improvement. The unit includes various adapters and a short hose, which can be extended with a 22.5-inch screw-on adapter. However, the extension uses a clamp-on chuck, which is harder to secure.
The pressure gauge on the unit tends to be inaccurate by about 5 PSI, so I still recommend using a separate tire gauge for accuracy. I tried inflating a tire from 30 PSI to 35, but the unit only reached 30. After adjusting the target pressure, it finally hit the right level. While it’s fast, it does drain the battery significantly — about 3% per 5 PSI.
Charging via the cigarette lighter didn’t work well due to the short cable, so I had to charge it separately afterward. It takes about an hour to fully recharge after inflating four tires.
**Charging Devices and Using the Floodlight**
The Halo Bolt Air has two USB-A ports for charging phones, but they’re slow and not suitable for tablets or fast-charging devices. Still, it’s handy in emergencies. The unit also includes an AC wall charger and a car charger, making it versatile.
The built-in floodlight is bright enough for basic tasks, but it’s not a replacement for a dedicated flashlight. It has three settings: white light, red light, and flashing red — the last being the most useful as an emergency beacon.
Overall, the Halo Bolt Air is a solid, compact tool for drivers who value convenience and space-saving design. It may not be perfect, but it gets the job done — and sometimes that’s exactly what you need.
