Overview
The NOCO Boost GB50 is a 1500-amp lithium jump starter rated for gas engines up to 7.0 liters and diesel up to 4.5 liters, built with spark-proof and reverse-polarity protection. At 2.7 lb it is sized for a glove box or backpack rather than a shop cart.
Its UltraSafe design is aimed at drivers who aren't confident connecting jumper cables correctly, since the spark-proof clamps and reverse polarity protection are built to prevent a bad connection rather than just warn about one. Reviewers who have owned it for years describe it holding charge and starting reluctant batteries repeatedly rather than degrading quickly, which matters more for this kind of device than the spec sheet.
- 1500 peak amps, rated up to 30 starts per charge
- Starts gas engines to 7.0L and diesel to 4.5L
- IP65-rated housing with rubberized over-molding
- 200-lumen LED flashlight with SOS and strobe modes
Who it's for
Suits drivers who want a compact, glove-box-sized jump starter for cars, trucks, motorcycles, ATVs or boats, especially anyone who wants foolproof clamp connections over raw peak amps. Less of a fit for someone who wants a larger lead-acid unit for continuous professional use.
What buyers say
From Amazon customer reviews.
Reviewers report the GB50 lasting several years of regular use, including one truck that gets jumped often after sitting more than three days, and several call out the clamps and housing as noticeably solid rather than cheap. A few mention the cable is USB-C on both ends, so charging from a standard USB-A wall adapter needs an extra adapter, and the carrying case is sold separately rather than included.
Strengths and trade-offs
Drawn from this product's published specifications.
- USB-C to USB-C cable needs an adapter for a standard USB-A charger
- Carrying case is sold separately
Performance notes
The 1500-amp lithium pack is rated for up to 30 jump starts per charge on engines up to 7.0L gas or 4.5L diesel, and the spark-proof clamps combined with reverse polarity protection are designed to prevent a bad connection from doing damage rather than just warning about it. Reviewers who have had the unit for years describe it starting a reluctant battery repeatedly without losing capacity, and the integrated power bank recharges in about 5 hours over USB-C.
