Halo Bolt Ultimate 2.0
Our Halo Bolt Ultimate 2.0 is the portable power station that keeps you running when you’re miles from an outlet. With 58,800 mWh of lithium-ion battery capacity, this compact unit jump-starts cars, trucks, motorcycles, and marine vehicles while simultaneously charging your phones, tablets, and laptops.
We built the Ultimate 2.0 for adventurers, road-trippers, and anyone who refuses to be stranded. The integrated 1000-lumen LED floodlight illuminates work areas or campsites, and the rugged housing withstands the bumps and drops of real-world use. Whether you’re tailgating, camping off-grid, or preparing for emergencies, this is the all-in-one power solution that earns its place in your trunk or garage.
Power & performance specs
Battery Capacity & Jump-Starting Power
The Halo Bolt Ultimate 2.0 houses a 58,800 mWh lithium-ion battery that delivers reliable cranking amps for mid-size vehicles. We engineered this unit to start gas engines up to 6.4 liters and diesel engines up to 3.2 liters, making it compatible with most passenger cars, SUVs, pickup trucks, motorcycles, ATVs, and small watercraft.
Unlike lead-acid jump packs, our lithium-ion chemistry maintains charge for months in storage and performs consistently in temperatures from -4°F to 140°F. The spark-proof jumper clamps prevent dangerous arcing during connection, and built-in reverse-polarity protection alerts you if cables are connected incorrectly. You’ll get multiple jump-starts on a single charge—typically 20 to 30 engine starts depending on vehicle size and battery condition—so one Halo Bolt can rescue an entire parking lot before needing a recharge.
Device Charging & AC Power Output
Multiple Charging Options
We equipped the halo bolt ultimate 2.0 with three USB ports and one 120V AC outlet to keep all your devices running. The dual USB-A ports each deliver 2.4 amps for standard smartphone and tablet charging, while the USB-C port provides 18W Power Delivery for fast-charging compatible devices like newer iPhones, Samsung Galaxy phones, and USB-C laptops.
The integrated AC inverter outlet supplies 65 watts of continuous 120-volt power, enough to run a laptop, CPAP machine, small fan, LED lights, or portable cooler. This makes the Ultimate 2.0 a true portable power station for camping trips, outdoor events, and emergency backup situations. The battery capacity provides approximately 4–6 full smartphone charges, 1–2 tablet charges, or 45 minutes of laptop runtime depending on your device’s power draw.
Integrated LED Floodlight & Emergency Features
The top-mounted 1000-lumen LED floodlight throws a wide, bright beam that illuminates engine compartments, campsites, or roadside repair areas. We built three lighting modes into the halo bolt ultimate 2.0: steady high beam for maximum visibility, emergency strobe for attracting attention, and SOS mode that flashes the international distress pattern.
This lighting system runs for up to 70 hours on a full charge in steady mode, making it a dependable backup during extended power outages. The floodlight’s wide-angle lens spreads light evenly across a 15-foot radius, and the recessed button prevents accidental activation in storage. Whether you’re changing a tire at night or setting up camp after dark, you’ll have hands-free illumination exactly where you need it.

Your Questions About the Halo Bolt Ultimate 2.0
The Ultimate 2.0 typically provides 20 to 30 jump-starts on a single full charge, depending on your vehicle’s engine size and battery condition. Smaller 4-cylinder engines require less power per start than larger V6 or V8 engines.
After each jump-start, we recommend recharging the unit when convenient to ensure it’s ready for the next emergency. The four-LED indicator shows remaining capacity so you’ll know when it’s time to plug it in.
Our Ultimate 2.0 safely jump-starts gas engines up to 6.4 liters and diesel engines up to 3.2 liters. This covers most passenger cars, SUVs, pickup trucks, motorcycles, ATVs, riding mowers, and small boats.
For larger diesel trucks or commercial vehicles, we recommend our <a href=”/halo-bolt-ultimate-4-0/”>Halo Bolt Ultimate 4.0</a> model, which provides higher cranking amps for heavy-duty applications.
Yes, the integrated 120V AC outlet delivers up to 65 watts of continuous power, which is sufficient for most laptop chargers rated at 45–60 watts. You can plug your laptop’s standard wall charger directly into the Halo Bolt Ultimate 2.0.
Typical runtime for laptop charging is 45–90 minutes depending on your laptop’s power draw and whether you’re using other ports simultaneously. The AC outlet uses a standard three-prong North American plug configuration.
The lithium-ion battery in the halo bolt ultimate 2.0 retains approximately 80–85% of its charge after three months of storage at room temperature. For maximum readiness, we recommend recharging every three months if the unit sits unused.
Unlike older lead-acid jump packs, our lithium chemistry experiences minimal self-discharge and performs reliably even after extended storage periods. The unit automatically enters sleep mode to conserve power when not in use.
Yes, we designed the Ultimate 2.0 to operate safely in temperatures from -4°F to 140°F, making it suitable for vehicle storage year-round. The battery management system includes thermal protection that prevents overheating and damage.
For optimal battery longevity, store the unit in a shaded area of your vehicle when possible and avoid leaving it on the dashboard in direct summer sunlight. The rugged ABS housing provides insulation and protection from temperature extremes.
The Halo Bolt Ultimate 2.0 includes spark-proof technology that prevents dangerous arcing when you connect the clamps to battery terminals. The built-in reverse-polarity protection detects incorrect cable placement and alerts you with an audible alarm before delivering power.
We also integrated overcurrent, overvoltage, and short-circuit protection to safeguard both the unit and your vehicle’s electrical system. These features make the Ultimate 2.0 safe for anyone to use, even without automotive experience.
Yes, you can use all USB ports and the AC outlet simultaneously, though total power draw affects runtime. The battery management system allocates power intelligently across all ports and will prioritize charging based on connected device requirements.
For example, you can charge two smartphones via USB while running a laptop on the AC outlet. Just keep in mind that using multiple high-draw devices together will deplete the 58,800 mWh battery faster than using one port at a time.
