Jump starter specs & power delivery

Battery Technology & Power Output
The Halo Bolt 55500 uses advanced lithium polymer cells that hold their charge longer than traditional lead-acid jump starters. Our engineers selected this battery chemistry specifically for its consistent power delivery in extreme temperatures, from freezing winter mornings to summer heat.
With 55500 mAh total capacity, you’ll get enough power to jump-start a dead battery 15-20 times on a single charge, depending on your engine size. The unit maintains over 80% charge capacity even after 12 months of storage, so it’s ready when emergency strikes.

Jump-Starting Capability & Vehicle Compatibility
This portable jump starter works with most passenger vehicles, including cars, motorcycles, ATVs, boats, and light trucks. We’ve successfully tested the halo bolt 55500 on gasoline engines up to 6 cylinders and 3.5L displacement.
For diesel engines or larger vehicles, you might want to explore our Halo Bolt 58830 model, which offers higher peak amperage. The 55500 excels with compact cars, sedans, and mid-size SUVs — the vehicles most people drive daily.
Portable Device Charging & USB Ports
Beyond jump-starting, the Halo Bolt 55500 functions as a high-capacity power bank for all your USB devices. The 2.4A port delivers fast charging for tablets and newer smartphones, while the 1A port handles older devices and accessories perfectly.
You can charge multiple devices simultaneously without affecting jump-start readiness. We designed the battery management system to reserve enough power for at least one engine start, even when the charge indicator shows partial depletion.

Common Questions About the Halo Bolt 55500
The Halo Bolt 55500 typically provides 15-20 jump-starts per charge for most 4-cylinder and V6 engines. Actual performance varies based on your engine size, ambient temperature, and how depleted your vehicle battery is.
We recommend recharging the unit after 3-5 jump-starts to ensure you always have reserve power available for emergencies. The LED indicator shows remaining charge levels so you know when it’s time to plug it in.
This model works with gasoline engines up to 6 cylinders and 3.5L displacement, covering most passenger cars, motorcycles, ATVs, boats, and light trucks. It delivers peak current suitable for compact sedans through mid-size SUVs.
For larger vehicles like full-size trucks with V8 engines or any diesel vehicles, we recommend upgrading to the <a href=”/jump-starters/halo-bolt-58830/”>Halo Bolt 58830</a>, which provides higher amperage output designed specifically for those applications.
The integrated AC wall plug allows the unit to recharge completely in 4-5 hours when plugged into a standard 110V outlet. We designed the charging circuit to prevent overcharging, so you can safely leave it plugged in overnight.
The LED indicators show charging progress, transitioning from red to green when the battery reaches full capacity. For fastest results, charge at room temperature rather than in extreme heat or cold.
Yes, the halo bolt 55500 can charge USB devices while maintaining full jump-start capability. Our battery management system reserves sufficient power for at least one engine start even when the charge indicator shows partial depletion.
You can safely use both USB ports simultaneously without affecting emergency readiness. The unit prioritizes jump-start power delivery, so your vehicle will always start when you need it most.
The lithium polymer battery performs reliably in temperatures from -4°F to 140°F, making it effective in both winter and summer conditions. Cold weather may slightly reduce total capacity, but the unit still delivers enough current to start most engines.
For best performance in freezing temperatures, store the Halo Bolt 55500 inside your vehicle cabin rather than the trunk. This keeps the battery closer to optimal operating temperature and ensures maximum power output when you need to jump-start.
The LED power indicator displays remaining charge in four increments, from full (four lights) to critical (one blinking light). We recommend recharging when the display shows two lights or fewer to maintain readiness for emergencies.
Even when stored unused, the unit naturally loses approximately 3-5% charge per month. Check and recharge your Halo Bolt 55500 every 3-4 months if you haven’t used it to ensure the battery maintains optimal health and capacity.
We back every Halo Bolt 55500 with a comprehensive warranty covering manufacturing defects in materials and workmanship. This includes the battery, charging circuitry, jumper clamps, and housing.
Normal battery capacity degradation over time and damage from misuse (like reverse connection or water exposure) aren’t covered. Register your unit within 30 days of purchase to activate full warranty protection and receive product updates from our team.
