THE SHORT VERSION
At a glance
Price $290 Weight 9.8 lbs Key Feature Jump-start capability and onboard tire inflation in one compact unit. Best Use Remote vehicle travel where a dead battery or low tire could create a long delay because outside help is not readily available.THE FIELD VERDICT
Why it stays in the kit
I bought the NOCO Boost+Air AX65 because I wanted more capability than my older GB40 and liked having air built into the same unit. After an easy first test with a low tire, it later started my truck on remote logging roads near Rangely, Maine, and a friend's Silverado after a fishing trip. It has proven exactly why I carry a jump pack, although the battery leads are frustratingly short.
FIELD PERFORMANCE
HOW IT PERFORMS
Low-Stakes Learning Curve
The inflator felt simple to use during the first TPMS event, and I was comfortable with the unit before needing it for a remote recovery.
Remote Jump Start
The AX65 started my truck immediately after the battery died on logging roads near Rangely, Maine.
Second-Vehicle Jump
It also started a friend's 2015 Chevrolet Silverado when that truck's battery unexpectedly died after a fishing trip.
Integrated Air
The built-in inflator let me address a tire that had dropped to roughly 33 PSI from the approximately 40 PSI I normally run.
Battery Lead Reach
The leads were frustratingly short on the Silverado and forced me to position the AX65 awkwardly to connect both clamps.
Remote Recovery Utility
In the Rangely event, the AX65 prevented a dead battery from becoming a multi-hour recovery involving a hunting buddy and satellite communication.
WHAT WORKS
Pros
- Integrated jump pack and tire inflator
- Jumped two dead vehicles immediately in the situations described
- Inflator was simple to learn during a low-stakes test

WHY I BOUGHT IT
More Than a Replacement for My Old Jump Pack
I had carried a NOCO Boost GB40 for years, and it had never really given me a reason to replace it. I bought the AX65 because I wanted an upgrade: more jump capability and, especially, onboard air in the same unit. The first opportunity to use it came when my TPMS showed one tire around 33 PSI instead of the roughly 40 PSI I normally run. That was almost the ideal introduction. The inflator felt faster and easier than I expected, and I got familiar with the AX65 before there was anything meaningful riding on it.WHY IT STAYS
It Keeps Small Problems Small
The AX65 stays in the truck because it has already done exactly what I carry recovery gear to do. It started two dead vehicles without turning either situation into a bigger event, and the Rangely jump mattered most because there was no easy backup plan. I had an inReach and could have called for help, but that would have meant involving somebody 15 or 20 miles away and waiting for them to reach me. The AX65 let me handle the problem myself and keep moving. Now I make sure it is charged before trips.BEFORE YOU BUY

BOTTOM LINE
Key Takeaways
Test It Before You Need It My first AX65 use was a simple low-pressure tire, which gave me a chance to learn the unit without stress before I ever depended on it remotely. Independence Matters More Off Pavement Eight or nine miles from pavement without cell service, a dead battery is not necessarily dangerous, but it can become a long recovery problem fast. Jump Power Has Been Immediate The AX65 started my truck near Rangely and later started a friend's 2015 Silverado with a failing battery, both without drama. The Leads Are the Real Compromise The compact body is easy to position, but the short battery leads can give back some of that flexibility when terminals are awkwardly placed. Not Every Emergency Tool Needs a Hero Story The AX65 earned its place by saving time, dependence, and hassle. That is useful enough.DECISION SUPPORT
How it compares
My direct comparison is the older NOCO Boost GB40 I carried for years. The GB40 had never failed me, so this was not a replacement driven by distrust. I moved to the AX65 because I wanted more capability and integrated air. That combination has made the newer unit more useful to me, although the narrative does not support broader performance, specification, or reliability comparisons between the two.FINAL THOUGHTS
It Did Not Save My Life. It Saved My Day.
The Rangely situation is why the AX65 stays in the truck. I was not in a survival situation, especially with an inReach available, but one dead battery could have turned into hours of waiting on somebody else because of one stupid mistake. Instead, I hooked up the AX65 and left. That is enough for me.KEEP GOING
