NOCO Boost Pro GB150 Review

NOCO's Boost X line redrew the lineup around USB-C a few years ago, but the GB150 predates it — one of the last of the original GB-series flagships, sized between the 2,000A GB70 and the 4,250A GBX155. This guide flagged it as a WATCH candidate for five consecutive scans because the Amazon listing kept returning a confirmed title with no live Buy Box price, which made it impossible to verify despite real market presence at dealers like Defender and Battery Junction. That's resolved now: the listing (ASIN B015TKSSB8) is live with a $299.95 price, in the same band those dealers have carried it at for a while.

The spec sheet is why it was worth the wait. A 3,000A rating with a 9.0L gas and 7.0L diesel ceiling sits in real, previously uncovered territory in this guide — well past what the GB70 or GBX75 are rated for, without reaching for the GBX155's biggest-truck numbers. The 88Wh cell is nearly triple the GB70's capacity, which shows up as more cranks per charge on a stubborn engine, and the 500-lumen flashlight is brighter than anything else in the lineup short of the GBX155. A 12V accessory output rated to 15A also means it can run a plug-in tire inflator, something the GBX75 above it can't do.

What you give up is the one upgrade that's defined NOCO's last few years of jump starters: USB-C fast charging. The GB150 charges the old way — a slow port that takes most of a day to refill from empty, instead of the one to two hours the GBX75 and GBX155 manage over 60W USB-C. For a pack that otherwise competes well on amps, engine coverage, and price, that's a real ding, and it's worth asking whether the GBX75 at a similar price with faster charging suits your engine size just as well. But if 9.0L gas or 7.0L diesel coverage at this price is what you need and charge time isn't a priority, the GB150 is finally a real, confirmed option again.
