NOCO Boost Air AX65 Jump Starter with Air Compressor Review (2026)
Updated September 14, 2026 · Research-based review
Our verdict
The NOCO Boost Air AX65 combines a 2000A jump starter with a 100 PSI air compressor, which fits overlanders who air down for trail traction and need to air back up before the highway. It costs more than a jump pack alone, and running the compressor uses charge that would otherwise go toward a jump start.
The NOCO Boost Air AX65 pairs a jump starter with an air compressor, suiting overlanders who air down tires and want one combined tool.
Price range: $$$ (Premium)
What we liked
- + Built-in air compressor refills tires after airing down on trails
- + Combines two roadside tools in one case, saving cargo space
- + NOCO brand backing and safety clamp design for confident jumps
Trade-offs
- - Higher price than buying a basic jump pack on its own
- - Compressor use drains the battery, leaving less charge for jumping
Who the AX65 is built for
NOCO markets the Boost Air AX65 as a jump starter, tire inflator, power bank and flashlight combined into one case, rated for gas engines up to 8.0 liters and diesel engines up to 6.0 liters. That combination is aimed squarely at overlanders and off-road drivers who deflate tires for grip on sand, mud or rock and then need to reinflate them before returning to pavement, since carrying one device instead of two saves cargo space. Daily commuters who just want backup jump starting can get by with a simpler, cheaper NOCO Boost unit, but anyone who already carries a separate compressor and jump pack can consolidate both into this single tool.
Jump starting and compressor specs
NOCO rates the AX65 at 2000 peak amps for jump starting, using UltraSafe technology with spark-proof connections and reverse polarity protection so the clamps will not spark or cause damage if attached backward. The built-in air compressor is rated to 100 PSI with a digital display for setting a target pressure between 15 and 100 PSI, moving roughly 67 liters per minute of airflow and handling tires up to 35 inches. NOCO states the compressor can take a tire from 0 to 40 PSI in about 2 minutes, or top off a low tire in under 22 seconds, and the compressor and jump starter draw from the same internal battery rather than separate power sources.
Using it on the trail
In use, the AX65 packages a 3-foot braided inflation hose, booster clamps, adapters for Presta valves, needle valves and inflatable toys, a USB-C charging cable and a microfiber storage bag, so most tire and jump starting jobs are covered without buying extra parts. The internal power bank also outputs up to 60 watts over USB-C, enough to fast charge a phone or small laptop, and a 100-lumen flashlight with multiple modes doubles as camp lighting. Because the compressor pulls from the same battery used for jump starting, airing up several tires in a row will reduce the charge available for a jump start afterward, so it is worth recharging after heavy compressor use rather than assuming a full jump start is always ready.
How it compares with other NOCO jump starters
Against the NOCO Boost Plus GB40, a smaller 1000A unit without a compressor, the AX65 trades pocket sized compactness for the added air compressor and higher peak amperage, at a higher price. The NOCO Boost HD GB70 offers 2000A jump starting similar to the AX65 but skips the compressor, making it a lighter choice for drivers who already own a separate inflator. Compared with the WOLFBOX MegaVolt16, a rival air compressor jump starter, the AX65 leans on NOCO's UltraSafe safety record and established clamp design, which matters for anyone jump starting unfamiliar vehicles at a trailhead.
Verdict and who should pick something else
The AX65 earns our score of 8.4 out of 10 by combining two genuinely useful trail tools into one well built case backed by NOCO's safety features. It is the right pick for overlanders and off-roaders who air down regularly and want one device for both jump starts and tire refills. Choose a simpler jump starter like the NOCO Boost Plus GB40 instead if you never air down tires and mainly want a compact, affordable backup for dead batteries, since paying for a compressor you will not use adds cost without adding value.
Frequently asked questions
What is the AX65's peak jump starting amperage?
NOCO rates the Boost Air AX65 at 2000 peak amps, suitable for gas engines up to 8.0 liters and diesel engines up to 6.0 liters.
How fast does the air compressor fill a tire?
NOCO states it can take a tire from 0 to 40 PSI in about 2 minutes, or top off a low tire in under 22 seconds.
Does using the compressor drain the jump starting battery?
Yes, both functions draw from the same internal battery, so heavy compressor use leaves less charge for a jump start until it is recharged.
What size tires can the compressor handle?
NOCO rates the built-in compressor for tires up to 35 inches, with a maximum output of 100 PSI.
