From the manufacturer
Designed for gas engines up to 6 liters (3L diesel) for cars, trucks, boats, motorcycles & more.
Power to spare.
The UltraSafe lithium battery inside NOCO Genius Boost can deliver up to 20 full power jump starts per charge. Best of all, it's protected by multiple levels of safety. Nothing happens if you touch the clamps together or hook up to a battery backwards. Boost not only provides a massive amount of power to start an engine, it also protects you from it.
Full power jump starting.
'joules 3s' represents the actual amount of power delivered in 3 seconds. Beware of jump starters just claiming high amperage ratings, as amps without time and voltage mean absolutely nothing.It works on a wide range of vehicles including cars, trucks, motorcycles, boats, ATVs and more.
Recharge USB devices.
Includes a built in 2.1A USB OUT port that can be used to charge virtually any USB powered device, like a smartphone tablet, GPS and more. In addition, there is a 2.1A USB IN port that allows Boost to be recharged from any powered USB port, like a phone charger or laptop.
Ultra-bright flashlight with SOS.
Whether you need light to change a tire, inspect an engine, or need to warn oncoming traffic that you are broken down on the side of the road, the ultra-bright dual LED flashlight in Boost have you covered. There are 7 built-in light modes, including SOS and emergency strobe.

A few things I have noticed to get the most out of it.
1. After use, plug it into your 12V cigarette light to charge it. This way it's always ready for the next time and it's the most efficient way to recharge the battery.
2. When jump starting large diesel trucks, don't use the jump starting posts unless you have to. Clamping directly to the battery posts will give you the best results. There have been times when I have used the jump starting posts only and the engine would crank over slowly. When I clamped on straight to the batteries the motor started right up!
I have now had a chance to use this booster/jumper twice to start cars with dead batteries, and it has worked well in each situation. It was so quick and easy to pull out this charger from my truck and jump start another's truck and an SUV. The truck is a 6.2 liter engine, and even though the GB40 limits its recommendation to engines up to 6.0 liters, it cranked over on the first try. Talk about impressive!
I hate fighting with cables. They are larger to store, have distance limitations, have the possibility or crossing the connection, and are a pain to fold back into their undersized pouch. This is so much easier. After two uses, the lighted readout still shows the Genius Boost Plus GB40 at 100% capacity, so I won't need to recharge it yet. I like the features that don't allow you to reverse the polarity on the clamps, as well as the ability to recharge anything via two USB ports. The included light is very helpful in the dark. It comes with a nice storage pouch, which is smaller than my old jumper cables, and it keeps all the charging accessories together.

Update: 12/10/2016* Used it a couple more times and I haven't even recharged it yet from the original charge.
Update: 03/23/2017 I bought a Land Cruiser for winter time driving and maybe some off-road adventure so I bought a second one of these bad boys for that vehicle. It isn't a problem at all, however I would like them to start offering a hard case for this for future customers. I am probably going to buy one for this. Still works great.
