DieHard 71687 950 Peak Amp 12V Jump Starter with USB/12V Portable Power Ports and 150PSI Air Compressor

Absolutely amazing product!! Highly recommend that you keep one in your vehicle. I'll break down what I've used it for and what I like.USB ports: charge well in about the same time as plugging into a wall outlet. Be careful with the on/off as it does not automatically turn on when you plug in a device. The on/off for the USB is a different button than the inverter power button.Car outlets: both work normal if you operate within the proper power draw.AC outlets: very handy. They work as they should. I've used them for speakers, fans, lights, etc.Air compressor: worked well for airing small toys and balls. Have not used it on a car tire yet. It come with a couple if attachment including a needle so you don't have to worry about keeping up with them separately.Jumper cables: WORK HORSE. The day after I got this my car broke down (turns out I needed a new alternator). I used this pack to jump off the car 6 times on one charge AND ended up hooking it directly to the battery to get the car home. Yes I know that is not technically what you should use it for, but you gotta do what you gotta do. After all that I got home and the pack was still on 47% of battery.Personally I am very impressed with this pack. I bought it as an alternative for a generator to power electronics at tailgate parties. My Beats by dre Beatbox portable speaker uses about 1% of battery per hour. Running a standard box fan uses about 25% of battery per hour. Lights-- depending on the kind-- vary greatly. I used a college dorm style 5 bulb lamp that used about 30% of battery per hour. A normal lamp uses about 10% per hour. A strand of Christmas lights use minimal battery.This is my experience with the pack. I tried to provide as much detail as I could for someone who is looking to use this the same way that I did. The work light on the top is not too powerful but will help in a bad situation. The thing takes a long time to charge when plugged into a wall outlet. Plan on overnight and don't worry about it. I hope this helps!!

My old Husky Jump Starter finally died...it was a slow and sad death. I went to Amazon to purchase a new one..but as always, there were endless choices. I scoured through many units, reading reviews and user experiences. None of the models in my price range had sterling reviews. So that made my decision much more difficult. I finally decided to try this one. The day it arrived was the first day it was used to jump start a car for my tenant. To my surprise, it started on the first turn of the key. Now THAT was impressive. A tire on my car has a slow leak so it has been used several times for tire inflating. It fills to the right pressure but it is not fast. It is louder than most inflaters that were previously owned, but it does get the job done. The pressure gauge is reasonable accurate. It says to keep the unit always charging. I do not care for that. I prefer to charge it and have enough battery power to get maybe a month before needing the recharge. There is an LED on the front that indicates the remaining power. It has been unplugged for two weeks and the LED still shows green...meaning that it still has sufficient power. When it turns to orange, I will plug it in. Overall, I am pleased with this purchase.

My Inifiniti FX45 was sitting in the garage with a dead battery. The battery was bone dry as I had not started it in 2-3 months (or more?). I tried jumping it with my other SUV but no luck. I looked online for a jumper and found several but this one got good reviews. There were a couple of others that got good reviews (Dewalt and couple others)... But this one also had other functions besides a jump starter, like an inverter for 2 AC outlets and a tire compressor too. So I went for it.I got it in 2 days from Amazon. Out of the box it already showed 100%. I still plugged it in to charge it and in less than an hour the light was pulsing indicating a full charge. I hooked it up to my FX and it started clean! without any stalling (my FX is a 5.2L V8 engine)... I had to jump my FX one more time and it did great the second time as well. So I am very glad I got it.UPDATE: One week later.Used the DieHard for 2 more jumps to my FX (without recharging) and it still worked on first try! Now I have plugged it back in for recharging. Still shows 100% but I left it to charge anyway.Glad I have this unit!
