These things are amazing, More people should know about them!
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!

Worked Well on My Dead Truck Battery
Bought this as a precaution. 1 or 2 weeks later the battery in my truck started dying. This begs the question, would my battery have died if I didn’t buy this jump pack?Anyway, easily jumped the 4.6L V8 in my F150. I am a lazy guy when it comes to auto repair, and the truck battery would charge enough to start most of the time, so I used this jump pack for a couple of weeks before replacing the truck battery.I could get 4 or 5 jumps off of the pack before it got down to 1 bar and I felt it needed to be recharged. It never failed to jump the truck immediately every time I needed it to.I knocked a star off because the contacts in the plug end of the jumper cables seem to be getting loose. They seem to push back into the little plastic box a bit, and I might have to take that little box apart to glue or wedge something in there to fix it.Might just be a defect on my unit. I never dropped or misused this thing, so I know it wasn’t something I did. It still works though, and overall, I’m pleased.

Always carry jump leads. 9 times out of 10 you’ll need them.
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.

Ignore the one stars…..
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.
