NOCO AX65 2000A Jump Starter with 100 PSI Air Compressor

Every boater has been there. You're at the ramp, or rafted up for the afternoon, and the engine just clicks. A dead starting battery can end a good day fast. The NOCO AX65 is the little box that gets you moving again. It's a 2000 amp lithium jump starter with a built-in 100 PSI air compressor, and it's small enough to live in a console locker or the tow vehicle's glovebox.

The jump starter side is the headline. 2000 peak amps is enough to crank engines up to 8 liters of gas or 6 liters of diesel, so this isn't just for your outboard's cranking battery. It'll turn over the truck that hauls the trailer, the diesel in a bigger cruiser, the tractor at the hunting camp, a motorcycle, an ATV. One tool covers the whole fleet. The pack is a 31.8 watt hour lithium-ion cell, so it holds a charge for months between uses and weighs a fraction of the old lead-acid boxes. And because it's lithium, it recharges fast and won't sulfate sitting in a locker all season.

Then there's the air compressor. 100 PSI is real pressure, not a toy pump. It airs up a trailer tire on the shoulder of the highway, tops off the dinghy or a paddleboard, and handles bike tires and pool floats with the included adapters. Set the pressure, squeeze the trigger, and let it run. You get a needle adapter for sports gear, a Presta valve adapter for high-pressure bike tubes, and an inflatable toy adapter for everything soft-sided. The compressor and the jump starter share the same pack, so it's genuinely a two-in-one you don't have to think about.

Power management runs through a single 12 volt DC / 5 volt USB-C input port and a 5 volt USB-C output. That means you recharge the AX65 over USB-C from a wall brick, a boat's 12 volt outlet, or a solar panel, and you can turn around and charge a phone or handheld GPS off the same unit. It's a power bank when nobody needs a jump. There's also an integrated LED flashlight for the times the battery dies after dark, which, let's be honest, is most of the time.

Who's this for? Anybody who runs gear that can leave them stranded. Center console owners who've watched a fish finder and a stereo drain the crank battery. Trailer boaters who want one unit that covers the boat and the tow rig. Anglers heading to remote launches with no help around. It's equally at home in a truck bed toolbox or a garage. If your world is one small outboard and a trickle charger at the dock, you may not need this much capacity, and that's a fair call. But if you run a mix of engines, this is the one box that covers all of them. Keep one in the boat and one in the truck and you've covered just about every dead-battery scenario a weekend throws at you.

A few honest notes from the water. Lithium jump starters give up some cranking punch in the cold, so in freezing weather give a stubborn engine a second attempt and let the pack rest a beat between tries. Keep the clamps clean and put a smear of dielectric grease on the terminals if it lives in salt air. And go easy on the flashlight when you're saving the pack for a start. Treated right, the AX65 is the kind of gear you forget about until the day it saves the trip.

The HD precision battery clamps are worth a word. They bite hard and hold a clean connection, which matters when you're leaning over a hot engine trying to get solid contact on a corroded terminal. Clamp on, start the engine, done. For a unit this compact, the build feels like it belongs in a working toolbox rather than a junk drawer.

In the box you get the AX65 unit, HD precision battery clamps, a 24 inch USB-C cable, the needle, Presta, and inflatable toy adapters, and a microfiber storage bag to keep it all together. It's covered by the full NOCO manufacturer warranty through us as an authorized dealer.
