The 130 PSI air compressor performed reliably on car and ATV tires, though it lacks auto-shutoff, requiring manual monitoring. Recharging via USB-C is fast, reaching full in under 4 hours, and the integrated floodlight offers solid illumination for night repairs. However, it doesn’t include an AC outlet or pass-through charging, limiting its utility compared to the Ultimate series. Still, for most users, its 8–10 jumps per charge and rugged build are more than adequate.
Against the HALO Bolt Air 58830, the Air+ 1750 is clearly the upgrade—offering higher amps, USB-C, and a superior display at nearly the same price. It’s perfect for truck owners, DIYers, or anyone in harsh climates who needs serious power in a portable form. While it doesn’t match the Ultimate 3’s full feature set, it delivers better peak performance than the Ultimate 2 at a lower cost, making it the best value for power-focused buyers.
