WOLFBOX 4000A Jump Starter,12V Car Battery Jumper Starter Portable with 65W Quick Charger,LED Display,88.8Wh Booster Jump Box Pack (10L Gas 10L Diesel Engine) with LED Light,Jumper Cables

Charged to full and placed in my car. Needed it the very next day. Easy hook up, worked perfectly. Something has drained my battery several times and I haven’t had opportunity to take the vehicle to the dealership. Whatever the problem is, it has only been happening intermittently. That being said this battery jumper gives me peace of mind for now and any future battery problems. Anyone could read the directions and be able to use it to jumpstart a car. Great item to carry in your car. Can’t speak to this item’s longevity but it seems to be well made. I carry it in a lower storage compartment in back of my suv. It’s a little larger than some I have seen so if you may want to measure if planning to carry in your dash/glove compartment.

Awesome jump starter, powerful yet compact and very easy to use. Highly recommended to carry in all vehicles and will jump start almost any engine ..

I have a 2004 Saturn Ion that I don't drive often and have a continuous issue with the battery draining just enough that it won't turn over the engine. Been using a 4 amp Battery Tender, but was looking for something more convenient. I first bought another brand of jump starter, but it couldn't start a little 2.4L engine. Gave Wolfbox a go and glad I did. I had charged the jump starter over the previous weekend, so it was ready to be tested. Charges quick, has some weight to it and doesn't feel cheap. Went out this morning, car didn't start. Followed the directions, got in, turned the key in the ignition, and the engine turned over and fired right up! Awesome tool! And it only used 2 percent of the charge.

This thing is awesome. Comes with a charging cable and block, is fairly light weight and has saved me multiple times now, on the same single charge. Its a little bigger than it looks like in the picture, but still small for what it is, and easy to store. I had a bad battery in my truck and used the boost mode and it jumped it right off. Did the same for my buddies truck and it worked again. The kicker is, I've used it 4 or 5 times now and only charged it once...and I still show 80% battery. This thing is a great for your wife or kids to keep in the car and I will be buying a second one for my wife. It is so much better than the big jump starters from the auto store, and we'll worth the money!

I could not be happier with my purchase! I lost my job and let my car sit idle for weeks. When I needed to run errands that I had saved to do all at once, my car didn’t start. I knew my lack of maintenance was the reason my battery had died. Regardless, I had to remedy the situation. I wasn’t sure whether to get a charger or a jump-starter. I decided on the jump-starter because I live in the desert and I didn’t want to be stranded somewhere being I couldn’t trust my battery to be reliable anymore. I charged it fully before using it. I admit I was a bit skeptical but it worked like a charm. I got all my errands done without needing it again. After a couple of days, my battery had lost all the charge it got from my day out. My battery was bad and needed replacement. I wasn’t ready to outlay the money for a replacement and I had a couple more errands that needed handling ASAP. I grabbed my Wolfbox, checked the percentage which was at 97% after a single use and went out to 3 different places. Each time I stopped, I needed the Wolfbox to start my car again. It was so easy to use and carry around. It is compact, light and hassle-free. After using it 4 times after the first, the charging capacity was still at 71%! The clincher for me was that it came with a hard-shell case to keep everything together neatly and organized. Using it didn’t cause any sort of commotion when I was using it out and about. In fact, one lady passing by commented how great it was to have one because it’d saved her when she was having electrical issues until it got figured out. It is basically fool-proof, although I recommend reading the instructions anyway. It looks very sleek and modern. Best of all, after leaving it in my hot car for a few days, the charging percentage was still at 71% which was a concern of mine and prevented my purchase sooner. This is a must-have for every single car. Peace of mind is priceless and this was really reasonably priced for the product. LOVE IT!!

Looks like a great bit of kit. Not used in anger yet. Good size digital read out and easy to use/read. Clamps are quite resistant but that means better gripping force. Arrived at 75% charge. Put it on charge and 100% was achieved within 30mins. Quite quick really. Supplied with storage case which is sturdy. Makes storing it in your car a breeze.

Funciona sin problemas

Great, until now. Didn't have the chance to try yet. Small size, powerful, and charges fast

Lo usé para una camioneta Tow & country con su batería totalmente descargada y prendió de inmediato. Lo recomiendo ampliamente
