   I have a few vehicles in my stable and they don’t all get driven regularly so sometimes they need a jump to get going and one of them is a 4.6ltr v8 triton motor.. everything else is v6’s engines. This jump pack has no issues jump starting everyone of them. I have bought other jump packs and returned them because they could not even get my truck to turn over, this one has no issues starting it within one or two whirls of the started from so dead the interior light won’t even come on. I am very happy with this unit and highly recommend it. The USB and 12 volt outlet on it are just a bonus! I also did not want the air compressor portion because they just use too much juice and make it heavy plus all my vehicles have their own 12 volt compressor on board in case I need one ( all of them are by Slime and plug in to the cigarette lighter plug ) so it was bonus for me that I found this one without the compressor.

   1 month review: This jump starter has been great and saved me from being late/ missing appointments several times already. On one charge I can be certain it will reliably start my VW Golf TDI at least 3 times. It starts up so fast its amazing.

   Pros:
   small and lightweight
   durable materials/ well made
   powerful and high charging capacity
   competitive pricing

   Cons:
   I honestly cant think of any right now, but ill be sure to update this review if I run into any problems

   I bought this when I knew my car was going to be sitting in a parking lot for over a week (instead of my garage where my car is normally parked and driven daily). When I returned, I didn’t want to get stuck if my battery was dead. I charged this device up and kept it in the back of my car while I was gone. When we returned to this lot, my car started right up. However, there was a family close buy who couldn’t get their SUV started. I ran over and hooked the device up to their battery and their vehicle started right up after that. The relief on their face said it all. The wife wrote down the info on this device and said she was going to order one immediately. Even though I didn’t need to save myself from headaches, it was nice to save another family who needed help.
   I have placed the device in the back of my wife’s car (I need to order another one for car), 2 months later, I checked the status of the charging power and the lights indicated that it was still good and didn’t need to be plugged in.
   I will recommend this device to all of my friends and family.

   Works fine as a booster. Being able to recharge it using the 12v socket is great, since I use a low power solar panel, situated in the back window of my car, plugged into the booster pack via the 12 v socket. This keeps the booster battery always topped up, which is very important if one wants to prolong the battery life. If the booster pack is used, however, it must be recharged using the 120 v system. The solar panel is just to maintain the battery, not recharge it.

   Doesn’t do very well at all for jumping vehicles with shot batteries- does amazing for holding voltage stable on a vehicle receiving various OBD updates such as pcm or ecm that it’s VITAL to keep good stable voltage. Very convenient to not have to plug every car into the wall to flash it, grab this and my laptop and off we go (most portable jump boxes turn off after 2-3 minutes, this one doesn’t so it’s much safer for long flashes because it won’t turn off sporadically mid flash, looking at you noco and clones)
   Ps the seller said it wouldn’t work for this use case and don’t buy it. Been a month and use it 5-6 times every day and does wonderfully.
   3 month update. Still working great to keep battery voltage at 12.0v while doing car updates. Still will only jump start cars with a weak battery. Bring a 10mm and a wrench with you. Completely unhook the old battery and put this in its place and it’ll start *most* things.

   Does not come with charging cable. It gives you 3 cables. Clips to connect to your battery. Cig lighter connector to jump start your car. Direct connect to your battery. Only thing that does not come with is a power cord. I tried it on a friends car and it jump started it with no issue.

    Did not use is much a few times. Does not work, the battery keeps dying and cant use for long on a single charge. Usless product and bad customer service. Tried to contact them and they dont honour their warranty. Would not recommed any of their products, unless product and wasted my money.

    The first one I bought for my husband a few years ago was great and still works great, we love it. The second one I bought for my daughter was the mid priced one, the lower price one had 3 USB spots and air pump, the one that was more expensive and I had bought my husband also had the 3 USB PORTS and air pump, the mid range one I got my daughter did not have the 3 USB PORTS or air pump. It was not clearly marked that it didn’t have the 3 ports, only one or that it didn’t have the air pump. Was very disappointed it that. But other than that would highly recommend the other two. Great price and works great too.

    Great product!. My truck has been sitting in the driveway. The battery was totally dead. This product started my totally dead F150 V8 5.4L truck *snap* just like that.

    Charged it up, all ready to go in case of emergency but sadly it didn’t work the first time I needed to use it. Not only could I not crank the engine but on troubleshooting there is no voltage/amps using a multimeter across the clamps even though the little worklight could turn on. Called tech support and went through troubleshooting – unit will not hold a charge. Bought in Jan and now it’s April so I can’t return it through ezysurvival.com and the warranty states that the customer has to pay return shipping for warranty service. Basically it’s now a very large, very expensive flashlight. If you buy it, test it out before the ezysurvival.com return period ends. I thought it was charged up because I clicked the battery button and all the battery lights flashed on. According to tech support, you have to hold the battery button down for 10 seconds. If the lights are not still lit at 10 seconds then the unit is not charged. This is not mentioned in the manual at all.
