WOLFBOX 2000A Jump Starter, 44.4Wh Battery Jumper Starter Portable with LED Display, 12V Car Battery Jump Starter Pack (7L Gas 6L Diesel Engine) with Booster, LED Light, Jumper Cables (NO Adapter)

Awesome jump starter. Easy to use, compact and just works. Useful to aid batteries in the frigid temperatures start ups. Used on Tractor after sitting in below freezing temps, robust on start. Only used 2% of stored energy. Nice readout. Only downside is the short cable. Not a deal breaker.

This jump starter is state of the art! It is extremely powerful and can jumpstart your dead battery as if it was fully charged. It also has ports for charging your phone, tablet etc. It is extremely easy to use and compact so that you can keep it in your vehicle at all times when needed. Very easy to use even for someone that has never had to jump start their vehicle before. You cant go wrong in buying this product. I would steer away from cheaper brands. It would do you well to stay with this product over others.

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.

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!!

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.

I would love to give this starter 5 stars, but for whatever reason it has to be on boost mode to start my Ram 1500. The charger that comes with it, the 65Watt wall box is phenomenal. It will start my truck, but I didn't think it would need to the boost.. I had to start an Outback wagon, no issues at all. Cranked right up. It's a great product for the money. I will probably buy a second one for my wife to have on standby.

I only recently learned about these jump boxes when my son's truck was having electrical problems that drained the battery. He had gotten one for Christmas and it came in handy during this problem. My truck has a 6-year-old battery in it and though it sounds strong, experience suggests that can change in a heartbeat. After researching several brands, I chose the Wolfbox 4000A. It's lightweight and comes with a decent storage case that fits neatly under the seat. It warns of incorrect connections and also tells you if you need to use the "boost" feature due to the battery voltage being under 9 volts. It comes with a wall charger, so recharging takes only 1-1/2 to 2 hours unlike the USB versions that can take many hours to recharge. I haven't had to use it yet, but I keep it with me because you never know. It is safer than jumper cables and doesn't require a second vehicle. I especially like the flashlight and SOS beacon that can be used in emergency situations.

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

Ik wil niet opscheppen ofzo, maar ik ben in bezit van een porsche boxter uit 1997. Deze auto's trekken gemiddeld een accu sneller leeg dan een andere auto. Nu was ik ook nog vergeten de FM adapter uit het dashboard te trekken, dus na 4 dagen: Alleen een klik bij het starten. Startkabels zijn geen optie in mijn carport, ivm met ruimtegebrek, dus maar een kijken naar een alternatief. Ik kwam de Wolfpack 4000 A tegen alhier en besloot de gok te wagen na het kijken van youtube recensies.... Ik ontving hem net, pakte hem uit, kabel erin en naar de auto...... Aangesloten, starten en : VROEM! Echt in 1 keer starten! Accu capaciteit was 75% bij aankomst en na starten, 74%. Dus als dit ding een 6 cilinder kan starten zonder problemen, kan ik hem alleen maar aanraden!

Muy buena estupenda
