    • Super fast jump by yourself
I grew up thinking long, thick jumper cables were the way to go. No way! This jump starter is amazing! Takes up little room and is so easy to use. It works well, you don't have to wait for your car to charge and you are on your way in no time without having to wait for another car to help jump you. Where has this been all of my life?! ... show more

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

    • A Lifesaver in Your Glove Compartment!
Rating: ⭐⭐⭐⭐⭐ (5/5) I recently purchased the NOCO Boost XL GB50 1500 Amp 12-Volt UltraSafe Lithium Jump Starter Box, and it's been a game-changer in my life. Not only is it a fantastic emergency tool, but it's also become my trusty companion on road trips and outdoor adventures. My boyfriend and I can't get enough of this small yet powerful device. The first thing that caught our attention was its compact and portable design. The NOCO Boost XL GB50 is incredibly lightweight and fits easily into the glove compartment or a backpack, making it an essential item to have on hand wherever you go. Its size is a major advantage, and it's impressive how much power this little box packs. The 1500 Amps of power in this jump starter is more than enough to jump-start our car, even in the coldest winter conditions. It's a relief to know that we can rely on this device when we're stranded with a dead battery. It has never failed us and has started our car without a hitch every time. The built-in flashlight is another feature that we've come to appreciate. It has proven to be incredibly handy when trying to jump-start the car in the dark or simply searching for something in our vehicle at night. The multiple lighting modes, including SOS and emergency strobe, provide added safety in various situations. The UltraSafe technology is a great assurance that we won't run into any safety issues. It offers protection against over-voltage, over-current, and reverse polarity, so we can confidently use it without any concerns about damaging our car or the device itself. The NOCO Boost XL GB50 is a versatile gadget that doesn't stop at jump-starting cars. It also serves as a power bank for charging our devices on the go. The multiple USB ports allow us to keep our phones, tablets, and other devices powered up while we're on the road. The NOCO Boost XL GB50 has quickly become an essential item in our vehicle. It's small and portable, yet it packs an incredible amount of power, making it an invaluable tool for emergencies and adventures. The built-in flashlight is a bonus that adds an extra layer of convenience and safety. My boyfriend and I absolutely love it, and I can't recommend it enough to anyone looking for a reliable jump starter and portable power source. ... show more
