NOCO Boost GB50 1500A 12V Lithium Jump Starter Power Bank Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
The NOCO Boost GB50 suits owners of mid-size SUVs and daily drivers who want a jump starter that doubles as a phone charger and flashlight at camp. Its strength is a 1500 amp rating that fits these engine sizes well, and its trade-off is that it is not built for large diesel trucks needing more amperage.

NOCO Boost GB50 is a 1500A 12V lithium jump starter and power bank, a middle option for mid-size SUVs and campers' daily drivers.

- + Power bank function charges phones when camp power runs low
- + Built-in flashlight helps when clamping cables at night
Trade-offs

Where it fits in NOCO's lineup
NOCO rates the Boost GB50 for gasoline engines up to 7.0 liters and diesel engines up to 4.5 liters, which covers most mid-size and full-size SUVs, trucks and daily-driver cars campers tow or drive to a campsite. It sits above NOCO's smaller GB40, rated to smaller engines, and below larger units like the Boost HD GB70 and Boost X GBX155 that NOCO built for bigger diesels and heavy equipment. For campers whose vehicle falls within the GB50's rated range, this middle-of-the-lineup unit avoids paying for jump-starting capacity beyond what their vehicle needs, while still leaving headroom over a car's actual starting demand.
Jump-starting power and battery
The GB50 delivers 1500 peak amps from a 35 watt-hour internal lithium-ion battery, and NOCO states it can deliver up to 30 jump starts on a single charge, so a fully charged unit can realistically sit in a vehicle for weeks or months of occasional emergency use before it needs a recharge. NOCO also states the battery holds its charge for up to a year, useful for a unit that mostly stays packed away until needed. A full recharge from a USB-C port takes about 5 hours at 2.1 amps, so campers who drain the unit jump-starting a vehicle should plan to recharge it before relying on it again.
Power bank and flashlight functions
Beyond jump-starting, the GB50 works as a USB power bank, with NOCO stating it can deliver up to 6 smartphone recharges from a full charge, which matters at a campsite without a reliable outlet. A built-in 200-lumen LED flashlight includes seven light modes, including SOS and emergency strobe settings, giving the unit a second practical use for late-night cable clamping, setting up camp after dark, or as a backup light source. Having jump-starting, device charging and a flashlight in one 2.7 pound unit reduces the number of separate gadgets a camper needs to pack for roadside and camp emergencies.
Safety features and build
NOCO built the GB50 with what it calls UltraSafe technology, which includes spark-proof clamp connections and reverse polarity protection so an incorrect or accidental connection to a battery terminal will not create a spark or damage the unit. The housing uses a rubberized, over-molded casing rated IP65 for water resistance, which suits campers who may need to jump-start a vehicle in rain or damp conditions at a campsite. NOCO includes HD precision boost battery clamps, a USB-C charging cable and a microfiber storage bag with the unit, backed by a 1-year limited warranty and free lifetime customer support from NOCO.
Verdict and who needs more power
For campers with a mid-size SUV, crossover or standard truck, the GB50's 1500 amp rating, IP65 housing and combined power bank and flashlight functions make it a practical single tool for both a dead battery and basic camp power needs. Owners of large diesel trucks or heavy equipment above the GB50's 4.5 liter diesel rating should step up to NOCO's Boost HD GB70 or a similarly rated unit instead, since asking this model to start an engine outside its range risks an incomplete jump. Because NOCO has released newer Boost models since this one launched, buyers wanting the latest features should compare current lineup units before deciding.
