Genius Boost Pro GB150 Jump Starter review

Whenever I see a new mini jump starter I just have to pick apart its specs and see what it can do. In this new age of special lithium-ion batteries powering these powerful jump starters, it’s nice to see some innovation.

NoCo has done just that with one of the most powerful Lithium Ion jump starters on the market. The GB150 is very compact, but also it is a lot larger than you tradition lithium Ion booster pack that is small and pocket sized.

I came across this high-performance jump starter the other day while out camping with my family. Some other people camping near us had the GB150 out. They were using this jump starter as a backup power device for charging their phones and tablets. So I took this opportunity to get to know my neighbors and learn more about the Noco heavy duty jump starter. I liked it a lot.

They had a large F150 pickup truck with the 5.0L Ti-VCT V8 engine. So a large amperage jump starter was required for if ever their battery died. It is nice to be prepared.

Energy Saving Auto Shut Off.

The GB150 has a built-in energy saving feature that will automatically turn the unit off after seven hours. If you want to use the Genius jump starter, just press the on button again.

The built-in voltmeter reads the car battery voltage, this is for enhanced diagnostics and troubleshooting. The LCD voltmeter will automatically read the voltage of any battery while the battery alligator clamps are connected, even if the Noco genius jump start unit is powered off.

The voltmeter will read voltage between 3V and 20V.

If the connected battery is below 3V, nothing will be displayed. If the voltage of the car or truck battery is that low, you will have to put the GB150 jump starter into bypass starting mode. Make sure that all AC fan, lights, and radio are turned off. This will provide maximum power to start the vehicle.

 

 

How to Recharge the GB150 Fast?

Noco uses a process called Rapid recharge by using special cables called XGC. You are able to recharge 4X faster with XGC compared to a traditional way of using a USB wall charger or computer USB port.

Charging options: Noco XGC cable with male-female converters and USB micro cable included.

The GB150 is completely rechargeable from any USB-powered port, like a wall charger, car charger, Anker folding solar charger, or laptop. But it will take around 11-hours. With the XGC cable, you can charge directly from the vehicle’s 12-volt auxiliary port in just over 3 hours. Even if your GB150 is completely flat just plug it into another vehicles cigarette auxiliary port and you will get enough power to do a jump start in just 15 minutes.

USB Charger Rating and Charger time of the GB150

Due to the internal battery on this super-sized jump starter, it will take a while to recharge it depending on the speed of your USB phone charger.

0.5A Computer USB port – 45hr
1A Phone charger – 22hr
2A Phone Charger – 11hr

The fastest way is to use the included XGC cable connected to your vehicle auxiliary battery port, also known as the cigarette lighter port from your car. Charging the GB150 using the XGC cable pulls out 5A at 12V (60W) so it should only take around 2-3hours to recharge from fully empty.

What is a Noco XGC cable?

NoCo has designed a system of supplying and receiving 12v without much voltage drop. This is due to the size of the cable being Duplex 16AWG. The connections are watertight have a nice compression fit so they won’t vibrate loose over time.

If you need an XGC extension cable to power devices like 12v air compressors and lighting, you can get them in various lengths.

The nice thing about the Noco GB150 is it comes with a female and male XGC auxiliary socket and plug. This then enables you to either charge the jump starter or power up other 12v devices with up to 15 amps of power.

 

How to do a Manual Override jump start on the GB150

If you have a totally dead battery less than 2-volts you will have to do a manual override. To do this connect up the GB150 to your battery and press the on button. You won’t see any voltage readout on the display due to the voltage being too low.

Press the exclamation mark button for a few seconds until the lights start to flash and then release. The NoCo will then be pumping out around 11.5v to the battery. This is enough to try for a start of your vehicle.

Peak Amps vs Cranking Amps vs Joules

It’s interesting and very confusing that some manufacturers list their jump starter product specifications in peak amps and cold cranking amps. Some manufacturers also list cranking amps, only amps, and some in mAh. Others even list joules like this NoCo unit to make life even harder.

So let’s look at the definitions of each….

Peak Amps definition – Peak power rating is the maximum demand spike that the Jump Starter can initially deliver safely. Usually only for a split second or two.

I recommend to always refer to the cranking amps when comparing jump starters of a similar rating. Most manufacturers are listing peak amp details as a sort of bragging rights but in reality is the cold cranking amps that can be delivered long term is the true real rating.jump starter peak amps current

Cranking Amps (CA) – Is the amount of power that a battery or jump starter can deliver/discharge for 30 seconds at 32° F (0° C). Its an average normal temperature that you would expect a battery to operate in all conditions. The colder a battery gets the worse its performance.

Cold Cranking Amps (CCA) –Is the number of amps that a battery can deliver for 30 seconds at 0° F (-17.7 Celsius) without dropping under 7.2 Volts (1.20 volts per cell).

Remember these mini jump starters are just another 12-volt battery linked in parallel which is supplying power to your car’s battery. It’s often more difficult to start an engine during cold weather due to thicker engine oil, and reduced battery performance. That’s why batteries tend to have both the CA and CCA ratings. The more information the better.

mAh – A milliampere-hour (mAh) is 1000th of an ampere-hour ( Ah ). It is the amount of power or energy charge that a battery can hold and deliver over a given time period. In layman’s terms, its how long an electrical device will run before its battery will need recharging.

Joules – Is the power rating that NoCo likes to rate their Jump Starters. As peak amps is only a quick instantaneous spike, Joules is more of a maximum power rating over time. As most cars, trucks, and boats start within 3 seconds, the GB150 is designed to deliver the greatest amount of power in this 3-second window.

What is the Joules rating of the NoCo GB150?

The Genius Boost Pro 4000A has a Joule rating of 22500 J/s over 3-seconds. The unit of energy is the “Joule” – One Watt is just a flow of one Joule per second.

Conclusion

The Noco Genius boost 4000 amp jump starter is one of the most powerful lithium jump starters around. Sure there are some bigger older traditional booster backs with lead acid batteries but these are heavy and take up a lot of storage space in your car, or 4×4 truck.

I believe this is the one jump starter to rule them all. Sure it’s not cheap but you would have to buy like 3 or 4 smaller models to be able to get the equivalent power output for jump-starting cars and recharging mobile devices.
