Product Reviews

Serious amperage that is very effective at starting engines up to a large V8. Eats other jump starters for lunch.

This review is for the GB 40 model. Sometimes reviews for all their models are shown together under each product.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 number cables, and it keeps all the charging accessories together.If you found my review useful to you, I’d appreciate you marking it as helpful below.

Excellent Product! Best Jump Pack Ever Purchased!

I am a garage foreman for a large electrical utility company, in charge of maintaining everything from trailers and forklifts to Ford F550’s and Heavy Duty International Trucks. I have purchased and used MANY different jump starters over the years. After another popular brand failed me in less than 90 days, I looked for something new. I found the NOCO Boost GB150 and was very skeptical of the 4000 Amps advertised. I purchased two of these 3 months ago and have to say I was and still am extremely impressed. I have been able to jump start 13.0L Navistar diesel engines with ease, something I thought wasn’t possible from a battery pack of this size. I use these almost everyday and multiple times in that day. I love being able to use a cigarette lighter 12V charger on my work truck to charge the battery. The digital voltage reading on the front of the battery is super helpful, to check for alternator/generator voltage.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!

4000 amps) This unit is awesome!!

I purchased the largest unit of these (GB-150, 4000 amps) This unit is awesome !!!! I am a Marine (Boat) Mechanic and run into Dead Batteries all the time and I Mean DEAD (less than 2 volts) This unit starts cold V8 engines like a new battery. I have tried all types of jump packs and this one is the lightest and most powerful of any I have tested. Now as far as the Amp rating (in this case 4000) I believe it is more marketing (Amps cumulative over time) VS actual delivered, for instance, I connected this unit fully charged to a 500 amp variable battery load tester to see what it could deliver, It maxed out at 420 Amps and held that for 20 seconds which is phenomenal !!! The units thermal protection kicked in after this. Realistically a modern V8 engine will average less than 200 amps while cranking and a 4 or 6 cylinder will be correspondingly less. Any engine will normally start within a few seconds. Now for some Battery FACTS ! Whenever a car battery (or any rechargeable battery) drops below a critical open circuit (no load) voltage (for 12 volt batteries this would be around 11 volts) internal damage begins and if one has a vehicle which drains a battery below this critical voltage (called a parasitic draw) you lose capacity every time a (what i call a destructive discharge) occurs. Under these conditions even a new battery may only last a few months and this applies to any type rechargeable battery Current rechargeable Lithium batteries would fail in one destructive discharge if protective circuits did not shut them off soon enough.
