TLDR; Worth the buy. Worked exactly as needed. Good tool to have on hand. "Better to have it and not need it, than need it and not have it." I had neglected to start up an 06 Infiniti sitting in the heat for a couple of weeks when the battery was already going bad. Don't judge! I bought a new car. So, since I always intended to own a portable jumper for times like this, having no cables & instead of bothering anyone with a jump, I pulled the trigger and bought one of these units. (12V 1500A) Getting to the point. Worth the buy. No problems upon use. I of course had to charge it completely which took somewhere between 4-6 hours. Upon hooking up to the battery ***it did take a minute or two for the car battery to "receive" the charge,*** but once it did, the unit started making a clicking sound, the power LED Indicators on the unit started cycling (which to me suggested the unit was officially feeding the car battery) - went to turn the key in the ignition and voila, car started up without skipping a beat. Remember folks, if a power cell has zero charge, it's not going to instantly come back to life when you hook it up to a jumper or other battery! Give it a couple of minutes at most, but any longer, it would be safe to assume the battery is totally dead especially if the unit is non-responsive when you hook it up. The unit itself is nice and compact. The box packaging is sturdy enough for you to regularly pack it back inside its box - if you're that sort of person, I am - but it does include a surprisingly NICE quality/material storage bag. The Jumper Cables are a tad short, but understandably for the purpose of being compact. I myself had no issues reaching my battery with them, but could pose an issue to those with a hard to reach battery. The dual LED illumination lights definitely supply you with some decent light, and would certainly be visible at night on the road or get you around your house in a power outage, but I would not recommend it be used as a primary light source. It also includes a USB port for you to connect a charger for your devices. I understand others have later reported that their unit died on them. I'll cross that bridge when I get there. Though, I would imagine as long as I don't keep it sitting on a charger, don't use it unnecessarily, and only recharge it if it actually becomes depleted - it should last. I recommend this product. 👌 Thank you for reading! ... show more

    • Excellent Jump Starter Box - will never go back to jumper cables.
Have owed the GB50 XL (1500A) for over a year and I've had to use it twice on my 2003 Chevy Silverado 1500HD Crew Cab (6.0 liter engine). Both times, it performed flawlessly under the conditions it was used. First time, on a nearly 5-year-old battery. Second time, on a newer battery that was being drained by a faulty A/C control unit that was purchased off Amazon (thinking it was either a bad refurb, or a cheap knockoff). Both times, the battery was below 2 volts as the Boost LED light was off (i.e. not illuminated). In those cases, below 2 volts, the unit didn't jump start the battery. Wouldn't even make a noise trying to turnover. Fortunately, it has a "manual override" feature. In those cases, I pressed the manual override button for 3 seconds as indicated in the instructions, and the truck sprang to life immediately. So not only does it work when needed, it's incredibly easy to use and very easy to connect. A far superior option that dealing with the much larger jumper cables and trying to (1) find another vehicle willing to help and (2) dealing with aligning them, if possible, to allow the cables to reach. Each of the 5 vehicles in our family has one of these, each rated appropriately for the size of the engine in them. As a bonus, they have built in lights that can be used in the dark if needed...and, they can be used to charge a phone if needed. We will never go back to using jumper cables. Only thing to remember is to keep this unit charged. We set a reminder to check the units 2x a year to make sure they are charged. Highly recommended! ... show more

CAR BATTERY DEAD? How often did you forget to turn off the interior lights? For how long did you not drive only to find out your car would not start? I lost count. My family, coworkers, strangers, and I all had that happen before, and when it did: - Was a jump start cable available? - Was anyone available to lend their car to power yours up with? - Did you know how to jump start a car? - Did you have a AAA membership, and did you have time to wait for a technician to arrive and help? My dad bought me a battery-operated jump start kit decades ago when I was in college. It was large and constantly lost its charge. Technology had changed since and small, powerful batteries now exist that can start a vehicle as large as a truck. MODEL GB40 PLUS (1,000 Amp) ---------------------- I had purchased a NOCO Genius Boost GB40 in 2016 for the sole purpose of having an emergency jump starter available for my SUV. Its feature set intrigued me: - Compact and portable at 2.4 lbs -- Does not need you to move your car so the battery could reach the other vehicle’s -- Just take out the NOCO, connect to your own battery, and start - Ability to jump start a 6L gasoline or 3L diesel engine -- My V6 engine SUV only uses 3.5L gas -- A Ford F150 truck with V8 goes as high as 5.0L - Up to 20 starts - Boost mode to send maximum charge to a completely dead battery -- 1,000 Amps — yes, really! -- This saved our butts many times — at least we were able to drive back home until we got our batteries replaced - Reverse-polarity protection to ensure you won’t short the battery if you connect the clamps wrong — FYI, red cable should always go to battery’s red or plus (+) terminal -- Having the clamps touch each other also does nothing. It’s quite fool-proof - microUSB re-chargeable in less than 3 hours - Battery to charge USB devices with - Built-in flashlight with SOS function - Battery maintains its charge for months MODEL GB50 XL (1,500 Amp) ------------------ I bought the 1,500 Amp NOCO Genius Boost XL GB50 model in 2019 to keep at home. - Can start a 7L gasoline or 4L diesel engine - Up to 30 starts - Battery recharges in 5 hours - Weight: 2.7 lbs, just 0.3 lbs heavier than the GB40 model USAGE Using the NOCO Boost is simple: - Ensure car is fully turned off, including all lights - Put car into Park and activate the hand brake - Pop open the car’s hood and wait 30 seconds - Plug the Boost’s red clamp to the car battery’s red or plus (+) connector -- Even if you plug it to the wrong one, the NOCO’s reverse-polarity protection will prevent your battery from getting short-circuited - Plug the black clamp to the car battery’s other connector - Turn on the Boost - Start the car and push down a bit on the gas to rev up the engine - If car starts, let it run for a few minutes -- Drive your car around for 30 minutes to charge up its battery a bit. It may simply need a few hours to fully recharge unless the battery is completely dead and requires a replacement Warning: Do not leave the car running inside your garage with the doors closed. You could get carbon monoxide poisoning and die! - If car did NOT start, wait 30 seconds -- Long-press on the NOCO’s Exclamation mark (!) button to activate maximum Boost mode -- You will see the light above the “12V 1000A” label turn on. This mode will send the maximum charge to the car battery -- Start the car and push down a bit on the gas to rev up the engine. It should work --- I had NOT come across a single car that could NOT be charged when the NOCO was set to its maximum boost The NOCO GB40’s small size once wowed a AAA driver when I showed him that it could start my mother-in-law’s completely dead battery. He showed me how large his one was. (That was not a dirty joke!) CONCLUSION This is one of the single, most important pieces of emergency gear I had purchased for myself and each family’s car — so you would not be stranded somewhere without a cell phone signal. Both models are very powerful, do not take up much space inside the vehicle, and are easy to use: my elderly mother-in-law remembered how to start her own vehicle after showing her just once! No more waiting for a tow truck/technician to arrive, and having been able to use the NOCO as a portable battery to charge my mobile devices with has been an added bonus. ... show more
