Rated 3000 A, but the attached guide prints 4000 A
NOCO's overview and tech specs pages rate the Boost GB150 at 3000 amps peak, for gas engines up to 9.0 litres and diesel engines up to 7.0 litres, and the overview says up to 80 jump starts. The listing title and bullets use the same 3000 A, 9.0 L and 7.0 L figures.
The user guide attached to this listing, headed NOCO Genius Boost PRO GB150, gives a different peak figure. Its technical specifications list a peak current rating of 4000A, and its manual override caution says that mode uses very high current, up to 4000 amps. It also says the GB150 can jump start most single-battery applications up to 80+ times on a single charge.
Neither NOCO document explains why the guide and the product pages differ, and we will not guess. The model number on the listing, GB150, is the one both documents use. If the peak rating matters to you, ask NOCO which figure applies to the unit being sold.
12-volt lead-acid only, with a built-in voltmeter
The guide says the GB150 is for jump starting 12-volt lead-acid batteries only and is not suitable for any other type of battery, and asks you to read the vehicle owner's manual for its own precautions. NOCO's tech specs page lists the battery type as 12 volt lead-acid, and the internal battery as an 88 watt-hour lithium-ion pack.
The GB150 has an integrated voltmeter. The guide says it reads the voltage of the vehicle's battery between about 3 V and 20 V whenever the clamps are connected, even with the unit off, and shows nothing below 3 V. The overview page also lists the integrated voltmeter.
The guide says the unit is designed for 12-volt lead-acid batteries down to 2 volts, and describes a manual override for batteries below that. Its caution states that both the spark-proof and reverse polarity protection are disabled in that mode, and ends by saying that if you are unsure, you should not attempt it and should seek professional help.
Charging times over USB and over the 12V fast charge
The guide's charging table gives 45 hours on a 0.5 A USB charger, 22 hours at 1 A and 11 hours at 2 A, or 2 to 3 hours on the 12V fast charge at 5 A and 12 V (60 W). NOCO's tech specs page gives the XGC input as 12 volts, 5 amps, with a 3-hour recharge. The listing bullet says it recharges in 7 hours, a figure that appears in neither NOCO document we read.
USB charging is rated up to 10 W through a USB IN port rated at 2.1 A. The 12V fast charge uses the 12V cable into the 12V IN port and the male plug into a 12V AUX port. The guide says the unit ships partially charged and must be fully charged before use, and that NOCO does not recommend charging and discharging at the same time.
The guide describes an energy-saving auto shut-off that turns the unit off after seven hours. It also lists a 12V OUT port for standard 12V devices up to 15 A, and a USB output at 5 V, 2.1 A.
The input port and box contents differ by document
The guide lists a Micro USB input and a Micro USB cable in the box, along with a 12V female plug for output, a 12V male plug for input, a 12V XGC cable and the user guide and warranty information. It does not list a storage bag.
NOCO's tech specs page lists a USB-C input and a box of the GB150, an XGC 12V male adapter, an XGC 12V female adapter, an XGC extension cable, a USB-C to USB-C cable, a microfiber storage bag and safety and warranty information. The listing bullets say USB-C cable and microfiber storage bag, while the listing's What's in the box block names the XGC connectors, XGC cable and USB-C cable but no bag.
Neither NOCO document explains the difference. Check which charging socket is on the unit you receive before buying a spare cable, and check the box contents against the list you were relying on.
Weight and size: 7.5 lb or 6.39 lb
The guide's specification table, NOCO's overview page and the listing all give 7.5 pounds. NOCO's tech specs page gives 6.39 pounds (2.9 kg). None of these says whether the figure includes the clamps and cables, and neither NOCO document explains the difference.
The guide gives dimensions of 12.3 by 7 by 2.7 inches, and NOCO's tech specs page gives a height of 7.28 inches, width 12.4 inches and depth 2.72 inches, which are close. The listing gives 8.19 by 4.88 by 13.7 inches and does not say whether that is the carton.
The guide gives operating temperatures of -30°C to +50°C, charging at 0°C to +40°C and storage at -20°C to +50°C as an average temperature. The housing is rated IP65 with the ports closed, cooling is by natural convection, and the LED light is 500 lumens with seven modes.
The warranty terms are not in this listing's guide
NOCO's tech specs page describes the warranty as a 1 Year Hassle-Free Warranty, and the listing states a 1-year limited warranty. The English pages of the guide attached to this listing contain no warranty text, and we did not open NOCO's separate warranty page, so this page cannot tell you the claim conditions.
The guide lists NOCO Support's phone number, 1.800.456.6626, and email address, support@no.co, which is where to ask about the 3000 A versus 4000 A figures, the input port and the warranty terms before you buy.
Because the warranty terms are not in the document attached to this listing, ask NOCO for them before you buy, keep your receipt, and check the seller and condition of the offer you select on Amazon.
