NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 7.0L Gas and 4.5L Diesel Engines

We think this is the best battery charger on the market. Have one in all of vehicles & gave many of our family members one for Christmas. They are durable, work well & are compact. Easy to use. Sometimes paying a little more is worth it for the peace of mind that the charger will work when you need it the most!

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!

This jump starter works great. I’ve used it on my 5.7L HEMI with a completely dead battery and it started right up without any issues. It’s easy to use, feels well-built, and the safety features give peace of mind. The size is compact enough to keep in the truck, but it has plenty of power when you need it. I’d definitely buy this again and recommend it to anyone who wants a reliable jump starter.

My late model F-150 sat for a colder than normal couple of weeks over the holidays, and when I went to start it, the battery didn't have enough juice to fire it up. I had wanted a jump pack anyway so I read some reviews and ordered the GB50. It came with a USB cord and a car power adapter for that, but no AC plug... not a huge deal, just something to keep in mind. I read the manual and then plugged its USB cord into an old Samsung phone charger I had sitting around waited until the lights went from red to green... roughly 2 hours from one red light to full green. I tried to crank the truck again but the battery was almost completely gone, almost no response at all. I then connected the GB50, waited for a few a seconds, heard it click, and then tried to crank the truck. It fired right up, no problem. So far I'm pleased. Build quality seems good, and the unit is lightweight and compact for the power it provides. Having a light wasn't something I was really looking for but might be useful at some point, and being able to function as a power bank for a USB device might be useful as well. I like that this unit has some protection built in, both in that I don't have to hook my vehicle up to someone else's if they need a jump, and for cross wiring if the unit was plugged in wrong. Note that for a very dead battery, there's an override option to turn the safety features off and just provide power, which might be needed if your battery is totally dead and the unit can't sense it once connected. I have a fairly new battery so I didn't need it this time, but for a completely dead one it may be required. Hopefully I won't need it again any time soon, but if I notice any issues in the future I'll update my review.

Buona qualità e affidabilità

Booster très qualitatif. Compact et pas trop lourd. J'apprécie la robustesse des pinces. Je précise que la charge se fait bien via un USB.C . Je recommande.

Only used once on a strangers car and it worked well. Held the charge for a while.

What a life saver to have this on hand, or in the back of your car! Gotten myself, friends and strangers out of trouble more than once! Well worth the price! Charges nice and quickly so you're not caught short, and ready to start your car when the power in your battery isn't up to the task! A nice sturdy build, and small enough to not worry about storing it anywhere specific!
