What NOCO rates the GB70 for
NOCO rates the Boost GB70 at 2000 amps peak, for gas engines up to 8.0 litres and diesel engines up to 6.0 litres. The amp and engine ratings appear on both NOCO pages and on the listing, and the overview page adds up to 40 jump starts. The guide's own specification table gives the same 2000 A peak current rating.
The guide is specific that the GB70 is for jump starting 12-volt lead-acid batteries only and is not suitable for any other type of battery. NOCO's tech specs page also lists the battery type as 12 volt lead-acid.
The listing's model number and manufacturer part number both read GB70, matching NOCO's documents, and the guide's regulatory text names Model Number GB70. NOCO's tech specs page gives the internal battery as a 56 watt-hour lithium-ion pack.
Protections, and what manual override turns off
NOCO describes the GB70 as spark-proof with reverse polarity protection, and the guide's troubleshooting table shows a solid red error light for reverse polarity and a blinking red light when the internal battery is too hot, with the instruction to let it cool. The enclosure is rated IP65, with the guide adding that the rating applies with the ports closed.
The guide describes a Manual Override button, held for three seconds, with a printed warning that it disables safety protection and manually forces Boost on, and that it is only for use when a battery is too low to be detected. If the Boost light does not come on, the guide's troubleshooting table gives a battery below 2 volts as the reason.
We are not reproducing the override procedure or the guide's connection sequence. Both are in the user guide attached to the listing; read those pages in full before the first time you need them.
Recharge times depend on what you plug it into
The guide's recharge table ties the time to the charger's rating: 28 hours at 0.5 A, 14 hours at 1 A and 7 hours at 2 A over USB, or 2 to 3 hours on the 12V fast charge at 3 A and 12 V (36 W). NOCO's tech specs page gives the 12V XGC input as 12 volts, 3 amps, with a 3-hour recharge. The listing bullet says it recharges in 6 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, from an AC adapter, car charger or laptop. The guide says the unit ships partially charged and must be fully charged before use, and that NOCO recommends not charging and discharging at the same time. Neither NOCO's box list nor the listing includes a wall adapter.
On keeping it ready, the guide says to avoid charging for more than a week at a time because overcharging may shorten battery life, that an unused product will discharge over time and must be recharged before use, and to disconnect it from power sources when not in use.
The input port and the box contents are described two ways
The guide's specification table lists a Micro USB input at 5 V, 2.1 A. NOCO's current tech specs page lists a USB-C input at 5 volts, 2.1 amps, and the listing says a USB-C charging cable is included. Check which socket is on the unit you receive before buying a spare cable.
NOCO's tech specs page lists the box as the GB70, 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's What's in the box block matches that closely; its bullet list leaves out the XGC parts.
The guide describes the 12V features in terms of a 12V cable with male and female plugs; NOCO's box list names XGC male and female adapters and an XGC extension cable. The guide says the 12V OUT port powers standard 12V devices up to 15 A, and that the 36 W fast charge goes into the 12V IN port from a 12V AUX port. NOCO's overview names tire inflators and power inverters as examples.
Size and weight: four sources, four answers
Weight is stated as 5 pounds in the guide's specification table, 5.0 pounds on NOCO's overview page and in the listing bullet, 4.18 pounds (1.9 kg) on NOCO's tech specs page, and 4.4 pounds in the listing's product details. None of them says whether the clamps and cables are included in the figure.
Dimensions differ too. The guide gives 8.6 by 6 by 2.5 inches. NOCO's tech specs page gives a height of 5.98 inches, width 8.74 inches and depth 2.76 inches. The listing gives 7.4 by 3.7 by 12.6 inches and does not say whether that is the carton. Neither NOCO document explains the difference, so confirm the size with NOCO if a storage space is tight.
The guide's temperature limits are -20°C to +50°C for operation, 0°C to +40°C for charging and -20°C to +50°C for storage, given as an average temperature. Cooling is by natural convection. The light is 400 lumens with seven modes: 100%, 50%, 10%, SOS, blink, strobe and off.
The warranty and its claim conditions
The guide attached to this listing gives a one-year limited warranty from the date of purchase, with repair or replacement at NOCO's discretion, subject to NOCO's technical support analysis. Replacement parts may be new or serviceably used. NOCO's tech specs page describes it as a 1 Year Hassle-Free Warranty.
The same guide says the warranty is for the original purchaser from NOCO or a NOCO approved reseller or distributor and cannot be transferred. To claim, you first obtain a return authorization number from NOCO Support, then send the product with that number and either your receipt or a warranty fee, and the purchaser prepays packaging and shipping.
The guide lists what voids it, including misuse, improper storage or operation beyond NOCO's recommendations, modification, and disassembly or repair by anyone other than NOCO, and excludes normal wear, cosmetic damage and units with a missing or altered serial number. Keep the receipt, register at no.co/register, and check the seller and condition of the offer you select.
