The review
The Boost X line sits a tier above NOCO's standard Boost GB models already in this catalog (GB20 and GB50) — the GBX55 steps up to 1750A, enough for larger trucks and SUVs with bigger gas engines or moderate diesels, while keeping NOCO's spark-proof and reverse-polarity protection.
USB-C Power Delivery is the standout feature: a full charge in 1.2 hours, or as little as 5 minutes plugged in to recover enough charge for one jump from a fully dead unit — useful if you forgot to charge it and need it right now. A 60-second engagement timer preserves the high-voltage design's charge between uses, rated for up to 9 jumps per full charge.
At 4,357 ratings and 4.5 stars, it's well-proven, though at $162.77 it's the most expensive jump starter in this catalog — a premium price for the extra amperage headroom and faster charging.
Pros
- 1750A — highest peak amperage of any jump starter in this catalog
- USB-C Power Delivery fast charging (1.2h full, 5min for one jump)
- NOCO's proven UltraSafe 2.0 protection
- Large review base (4,357 ratings)
Cons
- Most expensive jump starter in this catalog
- Only 9 jumps per full charge — fewer than some lower-amperage competitors
- Heavier and bulkier than NOCO's own GB20/GB50
Ideal for: Truck and larger-engine SUV owners who want NOCO's safety reputation with more amperage headroom than the GB50, and value fast USB-C charging.
What buyers say
4,357 ratings at 4.5 stars — buyers consistently praise the fast USB-C charging and NOCO's build quality, with occasional comments that it's pricier than needed for smaller engines.
