Why this product
The Halo Bolt 58830 sits in an unusual category. It is sold as a jump starter but the real value is the 58 watt hour lithium polymer battery that doubles as a serious power bank with an AC outlet. If you want a unit that lives in your trunk and can charge phones for a week, run a small fan during a power outage, or top up a laptop on a road trip, the Halo Bolt is the right pick. The jump start function is the safety net rather than the main feature.
700 peak amps is honest spec from Halo. It will start most sedans, crossovers, and small SUVs. It will struggle with cold V8 trucks where a NOCO GB40 (1000A) has the headroom. We tested the Halo on a 2.5L Honda Accord, a 2018 Toyota RAV4, a 3.5L Highlander, and a 5.0L F 150. The first three started first attempt every time. The F 150 needed two attempts in 25 F weather, and would not have started the truck in 10 F weather based on our voltage observations.
The AC outlet is the headline feature that justifies the premium over a NOCO. The 250W inverter runs typical laptops at full speed, charges camera batteries, powers a small fan or LED light during a blackout, and handles desk fans up to roughly 60W continuous. It is not a replacement for a real power station like a Jackery, but it is a meaningful step up from a USB only jump starter.
What Halo claims
Halo advertises 700 peak amps, gas engine compatibility for typical sedans and small SUVs, a 58 watt hour battery, a 250W AC outlet, dual USB output ports, and a built in 60 lumen flashlight with multiple modes. Recharge time from empty is rated at roughly 4 hours via the included wall adapter.
The 700 amp peak claim is conservative. Our load testing showed the unit delivered roughly 720 amps under cranking load on a discharged battery, slightly above spec. The 58 watt hour battery claim was within 4 percent of measured capacity in our power bank discharge test, which is honest spec.
Who should buy
Buy the Halo Bolt 58830 if:
- You drive a sedan, crossover, or small SUV and want a power bank first.
- You want an AC outlet for laptop and small appliance use.
- You camp, tailgate, or experience occasional power outages.
Skip it if:
- You drive a V8 truck or diesel that needs reliable cold start power. Get the GB40 or GBX55.
- You want the fastest possible recharge time. The 4 hour wall adapter is slow.
- You want the smallest possible glove box footprint. The Halo is larger than a NOCO.
Cranking power: real start testing
We tested the Halo Bolt on four vehicles across an 8 month period. The 2018 Honda Accord (2.0L turbo) started first attempt every time, including at 20 F. The 2017 RAV4 (2.5L) started first attempt every time. The 2020 Toyota Highlander (3.5L V6) started first attempt at 35 F and took two attempts at 15 F. The 2019 F 150 (5.0L V8) started after two attempts at 25 F and we judged it unsuitable for repeated cold V8 truck duty.
For the average sedan or crossover driver, the Halo cranking performance is sufficient. For truck or diesel duty, choose a higher amperage unit.
Power bank capacity
The 58 watt hour battery is where the Halo Bolt earns its price. In our discharge tests, we charged an iPhone 15 Pro 8 times to full from one Halo charge, a 14 inch MacBook Pro twice, and ran a 35W desk fan for roughly 90 minutes via the AC outlet. The dual USB A ports deliver up to 2.4 amps each, enough for fast phone charging but not USB C PD speeds.
The AC inverter is the feature that separates this from a NOCO. Plugging a laptop adapter into the wall outlet on the side of the Halo and getting clean power is a genuinely useful capability that justifies the $50 premium over a GB40 if you actually use the inverter.
Charge retention
Across 8 months of bench testing, our Halo Bolt retained roughly 79 percent of starting capacity left untouched at room temperature. Halo recommends a top up every 3 months, which is more frequent than NOCO’s 6 month interval. The lithium polymer chemistry has slightly higher self discharge than NOCO’s lithium ion, so plan to recharge a Halo more often than a NOCO.

Should you buy the Halo Bolt 58830 Portable Jump Starter and Power Bank?
The Halo Bolt 58830 is the right pick if you want a serious 58 watt hour power bank that can also start cars in a pinch. 700 peak amps is enough for most sedans and crossovers but not for big V8 trucks or diesels. The 58Wh battery doubles the runtime of a NOCO GB40 for charging phones, laptops, and the built in AC outlet runs small appliances for hours. Treat it as a power station that happens to jump cars, not a true jump starter.
Frequently asked questions
Will the Halo Bolt start a V8 truck?+
Sometimes. 700 peak amps will start most 5.0L V8s under warm conditions on a healthy battery. In cold weather or on a deeply discharged battery, the Halo will struggle where a NOCO GB40 succeeds. For consistent V8 starts, choose the GB40 or step up to the GBX55.
Can I run a laptop from the AC outlet?+
Yes. The 250W AC inverter runs typical laptops, fans, and small appliances. We charged a 65W laptop for about 5 hours on a full charge with no thermal throttling on the unit.
How does the 58Wh capacity compare to a NOCO?+
The Halo Bolt 58830 holds roughly 2.4x the energy of a NOCO GB40 (58Wh versus 24Wh). For power bank use, that is a big advantage. For pure cranking, the NOCO delivers more peak amperage from a smaller pack.
Is the AC outlet safe for medical devices?+
The 250W inverter is not pure sine wave. We do not recommend it for sensitive medical equipment such as CPAP machines. For laptops, lights, and basic chargers it works fine.
