[This review was collected as part of a promotion.] I recently had the chance to use the GearWrench GWLBJ12, and it honestly saved me from a stressful situation. A few weeks ago, I was heading out early for work when my car wouldn't start-completely dead battery. Normally, that would mean calling roadside assistance and waiting, but I remembered I had the GWLBJ12 in my glove box. Here's what stood out to me: 1. Serious Jump-Starting Power - The 1200A peak current had no problem starting my '99 4Runner's battery on a cold morning. It worked on the first try, which gave me a lot of confidence in its reliability. 2. Compact and Easy to Carry - Unlike older jump packs I've used, this one is lightweight and fits easily in the glove box or trunk. It doesn't take up much space, which is great for everyday carry. 3. Versatile Powerbank Features - The USB ports came in handy later that day when I needed to charge my phone. It's nice knowing this isn't just for emergencies-it's useful for camping or road trips too. 4. The display is clear and easy to read, and the included cables feel durable. I also appreciate the built-in safety features like reverse polarity protection, which makes it less intimidating to use. Overall, this tool turned what could have been a major headache into a quick fix. If you drive often or live in a cold climate, having the GWLBJ12 on hand is a smart move.

[This review was collected as part of a promotion.] The small and compact size of this unit makes it awesome to carry around. Used it to start a f150 on a -10 degree day. And fired it right up. Can easily fit in the glove box. I would buy one for each vehicle I own

[This review was collected as part of a promotion.] GWLBJ12 jump pack comes in a well packed box to keep things from breaking during shipping. There is a carry bag included, which works well. I used the GWLBJ12 on my work car on one of these cold Illinois mornings. Instantly started. I really, really like the instructions being printed on the jumper cables themselves. Very handy. I do wish the cables were another foot longer, but they work as is. The built in flashlight could be handy, but it's just an added bonus. Overall pretty impressed with this unit. Time will tell on seeing how long the charge lasts and how many starts I can get out of it before rechecking.
