NOCO U65 65W USB-C Charger for Boost X GBX45/55/75/155

If you run a NOCO Boost X jump starter on your boat, in the truck, or in the garage, the U65 is the wall charger that keeps it topped up and ready. It's the 65-watt USB-C power supply NOCO built specifically for the Boost X line, and it recharges a GBX45, GBX55, GBX75, or GBX155 up to five times faster than a standard USB wall plug or car charger. When you actually need a jump, a dead jump starter helps nobody. This is the piece that keeps yours full.

Here's why the speed matters. A jump starter is only useful if it's charged, and the big Boost X packs hold a lot of energy. Charge a GBX155 off a slow phone brick and you're waiting a long time. The U65 pushes a real 65 watts of USB-C Power Delivery, so the pack drinks it up and gets back to full in a fraction of the time. Plug it in when you get back to the dock or into the shop, and it's ready before your next trip out.

The output is proper USB-C PD: 3 amps at 5, 9, 12, and 15 volts, and 3.25 amps at 20 volts. That covers the fast-charge handshake the Boost X packs look for. And because it's a standard 65W USB-C brick, it'll also top off a phone, a tablet, or most USB-C laptops in a pinch. It's built for the jump starters first, but you're not carrying a single-use charger.

Travel with it. The U65 accepts 100 to 240 volt input at 50 to 60 hertz, so it works on outlets anywhere in the world, and NOCO includes four plug adapters in the box: North America (Type A), Europe (Type C), United Kingdom (Type G), and Australia (Type I). Snap on the one you need and you're set. For a boater who splits time between marinas, or anyone who travels with their gear, that's genuinely handy. No hunting for a converter at the airport.

The whole kit tucks into a protective EVA zip case, so the charger, the 24-inch USB-C cable, and the plug adapters stay together instead of rattling loose in a drawer or a dock bag. That EVA case is the kind of small thing you appreciate the third time you reach for the charger and everything's actually there.

Who's this for? Anyone who already owns a Boost X GBX45, GBX55, GBX75, or GBX155 and wants a spare charger, a replacement for one that walked off, or a faster way to recharge than a cable-only setup. Keep one at the house and one on the boat. Toss the EVA case in the truck. The point of a jump starter is that it's ready when you're stuck, and the fastest way to keep it ready is the charger it was designed around.

A couple of honest notes. This is an AC wall charger, so you plug it into a standard outlet, not a 12-volt socket. And it charges the Boost X packs. It doesn't jump start anything on its own, and it isn't the pack itself. If you need the actual jump starter, that's the GBX unit. This is the power supply that feeds it.

One more practical thing. Because the U65 is the same 65-watt supply NOCO matches to these packs, you're not gambling on an off-brand adapter that might under-deliver watts and slow-charge the battery. It's the right charger for the right pack, doing the fast recharge it was designed to do.

It's black, it's compact, and it does one job well: getting your Boost X back to full, fast, wherever you happen to plug in. That's it. Buy it once, keep the case handy, and you won't get caught with a dead jump starter because the charging was the slow part.
