   First, the price is excellent. Second, it shipped right away. Third, it was packaged well. Fourth, the actual product packaging (carrying case, cables, etc.) is very good. Fifth—and very importantly—it came fully charged! That was a vital feature, because I immediately needed it to started my grandson’s car. He had left the car with me during his summer college break, and the battery died unexpectedly. The car (a 2018 Honda Civic) was parked in a place where no other vehicle could come near it for a jump start. Right out of the box, this handy little unit started my grandson’s car 3 times in 2 days. So I was able to start the car, back it out of its tight spot and drive straight to AutoZone for a new battery. Easy-peezy! I’m delighted with everything about this handy charger—including the orange color (which I love)! You can spend more … but why would you? Highly recommended.

   I’ve had this for over a year now and have used it dozens of times. However it has only worked once or twice. If your car wont crank it’s useless, if your car is cranking but not fast enough to start it might just get you going but never rely on one of these, always carry jump leads as well. The problem with these is they only put out 12 volts when freshly charged, so if your battery is say 11 volts, they wont increase the voltage or charge your battery, they might just give you a few more amps to get you going if you left your lights on for 15 minutes while at the grocery store but will do nothing if your battery is dead in a no crank situation. How they claim to start a semi truck beats me as mine wont even start my Honda!
   If you like to get out there camping etc, where a jump is not an option invest in a professional lead acid battery starter or just carry a spare car battery. These Lithium packs are just an expensive gimmick.

   I have a buddy had this killer device charger he took with him on trips simply to have a large capacity for keeping his phone, laptop and things full. He spent well over $100 for it. I thought it was great.
   Here’s the thing, it can’t jump start his car too!
   Here is my point, for well over 25% less cost, this device does the same thing, even has a larger capacity then his… AND… in a pinch happens to be able to both jump start my truck, but also act as a long lasting emergency flashlight. Why would anyone buy one of those storage bank device chargers when these things exist? 21000mah.. this will charge any device well over 5 times from zero to full. this is a must have! It works great, has two USb inputs for charging multiple devices at the same time, built well, takes only a few hours to charge… and keeps its charge for a VERY LONG time. don’t hesitate. nab it. Great gift too!

   We have used this over a dozen times already. Not gonna lie i was concerned about this being too cheap and when I opened my first opinion is that it is just cheap plastic cause its so light however this way surpassed my expectations of a jump pack. It always shows 50% battery after two jump starts on my wife’s hyundai sonata but I’ve never chanced it and always recharged before 3rd jump. Like the title says it starts immediately no need to wait for charge just attach to battery and start. We bought this because we have battery problems in the winter and so far this has worked flawlessly at under 20° ambient temperature. The usb plugs also charge fast. The unit itself charges in less than an hour but like I said that’s at half life not from dead. I will update once I have a chance to full charge.

   What a great tool to have. My battery was dead after the car sat for almost 4 months. This things is 5.0 one jump and the car was running again.

   I read through the one star reviews and found them very entertaining. Most of the problems people had were because of their lack of knowledge. I’ve had mine for quite a while now. Once you understand how the electronics work, this thing is amazing. When you press the button and it shows 4 bars. That’s not for the jumpstart part of the box. Plug in to charge it and when it’s done blinking, it’s done charging. After hooking this up to the car, press the button on the cable module to reset it. Give it a couple minutes before trying it. I’ve jumped a completely dead dual battery monster diesel, 2 golf carts, my motorcycle, and a work truck off of a single charge. It does take a very long time for a full charge. 2 days the last time with a super fast charger for my cell. This actually my second one. First one I got for Christmas and got busted up from a fan blade. Be careful where ya put it when ya start the car. Lol. I threw out a junk Dewalt jump box that lasted less than a year. This unit is still running strong. After all this time it doesn’t jump as well. I can usually get 2 completely dead car batteries to start before charging it. Anyone that posts a one star review on this product should take it to their local mechanic and request lessons on using it correctly. For a tow truck to come jump start a car around here is $100+. This is a no brainer.

   This jump box is the greatest thing I’ve seen!! USB rechargeable, this jump box is compact and easy to use. Powerful enough to jump start your car or truck, and small enough to fit in the pouch behind your drivers seat. I’ve also used it to charge my phones during a three day power outage with its built in USB connection. Great buy!!

    I ordered the first one Aug30 and it was great! Lots of features and capabilities. See photos. you got a charger, dual USB outputs, a variable DC output 12,16,or 19v, 15 volt charger or use 5volt USB to charge all in addition to the starter capability and flashlight. Super! HOWEVER I used ezysurvival.com “buy it again” on Oct 31 to give one as a gift. The new one (with the same Model number A13) lost many of the useful features. A unpleasant surprise since the Model number is still A13! With the loss of many features the model number should have been changed which would have alerted me when I used “but it again” that it was not available anymore. Compare my photos with the current ad you will see the difference. I direct shipped to my gift recipient and didn’t know features were missing until discussing how to use something they did not have. Anyway it is still a good tool, just not quite a good as before. So 3 instead of 5…..
