Lovely little gadget, safe and very easy to use, GB40 is still on full power and its been sitting in the car for a month. Highly recommended, good price too. Read full review Unless you press the over ride, which cancels out the safety features, this little unit is safe enough even for me. Using the GB40 is very easy. My car had been standing idle for a month before using the GB40. When the gadget arrived I needed to power it from the mains for about an hour. I took it outside and managed to start my Diesel 2L on the second attempt. Most vehicles will immediately start. Some vehicles may require the GB40 to be connected for up to 30 seconds before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GB40 to rest for fifteen (15) minutes before attempting to jump start the vehicle again. Understanding Charge LEDs The GB40 has four (4) Charge LEDs - 25%, 50%, 75% and 100%. These Charge LEDs indicate the internal battery's state-of-charge (SOC). See below: LED Connect the GB40 using the included USB Charge Cable to the USB IN port and the USB car charger. It can also be recharged from any USB powered port, like an AC adapter, car charger, laptop and more. The USB IN port is rated at 2.1 Amps to ensure safe and efficient charging of the internal lithium battery. Due to FCC regulations, we recommend not to charge and discharge the unit at the same time. Charging Times
If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force "On" the jump start function.
GB250+ Boost Max
For those who require a lot more power than what the GB40 and GB50 can offer, you must fork out quite a bit more dollars for the GB70. Saying that, it still offers excellent value for the amount of power it carries, its added features, and a higher rating for jump-starting batteries. Recap: Which one should you buy? If your battery is below 12 volts, the Boost light will be off, indicating that the GB40 cannot detect the battery. Make sure your battery has a minimum voltage of 12 volts for the GB40 to function properly. Seven light modes including flashlight features for car hood lighting and emergency strobe for 100-Lumen LED light used at the front side. The NOCO Genius Boost+ GB40 is a compact and portable solution for jump starting a vehicle's battery on-the-go. The charger's small size allows it to be easily stored in a glove compartment or trunk for emergency situations. The single USB port allows for simple charging of mobile devices, making it a versatile accessory to have on hand.
One step up, GB50 will jump-start vehicles’ engines up to 7.0 liters for gas, and 4.5 liters for diesel. It will take 30 jump-starts to empty its battery of power. NOCO also upped the flashlight’s strength to 200 lumens. The absence of a built-in display is compensated for by the charger's construction with high-quality materials, ensuring its reliability and durability over time. The RoHS certification indicates that the charger adheres to European Union regulations and is environmentally sustainable. Designed for gas engines up to 6 Liters and diesel engines up to 3 Liters for cars, boats, lawn mowers and more.A: No. The GB40 is technically a jump-starter – not a battery charger or even a maintainer. The GB40 has only lead-acid battery compatibility, hence it cannot jump-start a lithium battery. Make sure to correctly connect the booster clamps to your vehicle's battery. Make sure to connect the positive clamp (+) to the positive terminal of the battery and the negative clamp (-) to the negative terminal. The GB40 has an integrated ultra-bright LED flashlight. It has seven (7) light modes that effect its performance and longevity: 100%, 50%, 10%, SOS, Blink, Strobe, and Off. This ultra-light and compact jump starter was designed to boost 12-volt batteries. It’s capable of jump starting gas engines up to six liters and diesel engines that are up to three liters.
Wait, how does that even work? You’ll be most impressed with the recharging capabilities of the GB70. Using the regular 2.1A power input, it will need 7 hours to recharge fully. If you charge it up with its 12-volt/15-amp/36-Watt power-in port, you can boost a dead GB70 to jump-start a vehicle in 15 minutes. To fully charge it will take less than 3 hours with that 12-volt/15A/36-Watt fast-charger. How do they match up on price? Compact, Advanced and lightweight design for carrying and using ease without having to worry about being helplessly stranded in emergencies. A: The majority of running vehicles are below allowed size, and so the NOCO Boost Plus GB40 will work with most car engine sizes. First, try resetting the device. To do this, simply remove the battery and then reinsert it. This should reset the device and hopefully fix the issue.The 75% Charge LED will slowly pulse "On" and "Off", when the battery is less than 75% charged. When the battery is 75% charged, the Yellow Charge LED will be solid. The 50% Charge LED will 'breath' on/off while charging and will be solid Red when the internal battery is 50% charged.
Looking for a jump? We researched 50 of the best jump starters available today before purchasing 9 to test side-by-side. We took an in-depth look at the performance of each option, utilizing load testers, multimeters, and clamp meters. Using these tools, we were able to assess power performance, functionality, and battery storage. We spent hours in our at-home lab looking at voltage and amperage in real time while charging different batteries and engines. After collecting the data, we compare each product to give you an in-depth overview, finding unique uses and caveats for the models that stand out; all to help you in your buying decisions.In The Box – GB40 UltraSafe Lithium Jump Starter, Needle-Nose Battery Clamps, 12-Volt Car Charger, Micro USB Charging Cable, Microfiber Storage Bag, User Guide, 1-Year Warranty, and Designed in the USA.
