WolfBox 2000A Car Jump Starter, Portable Battery Booster Pack, 12V Power Bank for 7L Gas & 6L Diesel Engines

I initially purchased a similar jump starter from Harbor Freight for approximately twice the price. I wanted something strong enough to start a v6 truck with a flat battery but compact enough to carry on my motorcycle when going on motocamping trips. This turned out to be exactly what I needed. The harbor freight jumper does have a larger overall storage capacity but that comes at the cost of size and weight. That may be a better option for someone looking to jumpstart a dozen vehicles a day. The Wolfbox has a smaller battery but just as much power which is better for my intended use of hopefully only needing 1-3 starts in an emergency. The light is more than bright enough to clearly see in an engine bay if you get stranded at night but isn't going to fill a room. The real key to making this great is the boost button on the jumper cable. Most jumpers check for voltage and will refuse to deliver power to a flat battery. With the boost button, this jumper will override that voltage check and give you the juice to get back up and running. Comes with a thick owners manual and a thin bag to store it in. The manual is easy to understand and can likely be tossed after reviewing once. I may get a hard shell case to store the jumper in since I could imagine the power gauge could get scratched up being stored in a bag. I bought mine with a warranty - not sure if I'll need the warranty but didn't mind throwing it in since it was so much cheaper than the one I returned.
