NOCO GB70 vs NOCO GB150: Specs at a Glance
Highlighted rows show where the two products differ.
NOCO’s early GB150 sell sheet listed 4,000 amps and 10.0L+ engines, but its current user guide rates the unit at 3,000 amps and 9.0L gas or 7.0L diesel.
Feature-by-Feature Breakdown
Starting power
The GB70 is rated at 2,000 peak amps and the GB150 at 3,000. What matters more is NOCO’s engine rating. The GB70 covers gas engines up to 8.0 liters and diesels up to 6.0 liters, which includes most passenger vehicles. The GB150 steps up to 9.0 liters gas and 7.0 liters diesel. Check your owner’s manual for displacement before ordering. If you are comfortably inside the GB70’s range, the larger unit does not start your vehicle any better.
Winner: NOCO GB150
Battery capacity and jump count
The GB70 has a 56 watt-hour battery and NOCO claims up to 40 jump starts per charge, while the GB150 has 88 watt-hours and a claimed 80. Automoblog notes the GB70 figure assumes ideal conditions, so treat both as ceilings. NOCO also says the GB150 can recharge a smartphone up to six times. For a single family car, the GB70 is plenty. For a shop truck or towing rig, the GB150’s reserve makes more sense.
Winner: NOCO GB150
Size and portability
The GB70 is about five pounds, and Automoblog describes a solid build with thick clamps and cables that it found possibly over-engineered for average drivers. The GB150’s unit weighs six pounds, rising to 7.5 pounds with clamps and accessories, per NOCO’s guide, and it is listed at about 11.8 by 7.3 inches against 8.6 by 6 for the GB70. If it lives in a glovebox or under a seat, take the GB70. If it stays in a truck bed or shop, weight matters less.
Winner: NOCO GB70
Extras and diagnostics
Both units share 2.1-amp USB output, a 12-volt accessory output, IP65 housing and a seven-mode flashlight. The GB150 is brighter, at 500 lumens against 400, and adds a built-in voltmeter that shows your vehicle battery’s voltage, which helps when you are trying to figure out why a car will not start. The GB70’s sell sheet does not list a voltmeter. For casual owners this is a nice bonus, but for anyone who works on vehicles it is useful every time.
Winner: NOCO GB150
Availability and safe use
Both models were on Amazon in June 2026 alongside NOCO’s newer Boost X units, such as the GBX75 and GBX155, so check whether a newer model suits you. NOCO’s GB150 user guide says to wear eye protection, operate in a well-ventilated area, not leave the unit unattended, and never jump a damaged or frozen battery. It also warns that Manual Override disables the safety features. Read your specific manual before first use and follow it exactly.
