I purchased 2 as Christmas gifts. My nephew has already used his twice. He has it charged and keeps it in the trunk in case of emergency. ex. (Using the compressor in case of a flat, the cable jumpers for the battery)

Me this scottish single dad of 2 wee disabled Lads gottae say TIS A nice blithe item very good an so much thanks tae Sams club fir constant quick caring service an shipping . ;-) Paul & Lads

Since this is typically an emergency use item, I haven't had a chance to really test it. I have used the compressor and it seems to be Ok other than being slow and quite noisy...it passes.

had to air up a tire while it was raining... unit got a little wet... unit died never worked again... guess it'd be a good fair weather emergency tool... unfortunately bad things don't always happen in fair weather....

I purchased 4 of this product for Christmas and my spouse battery died we hooked this wonderful thing up and the car crank in seconds. Love it so much I sent on to a family member in Alabama

Had for the hurricane. Holds a great charge, haven't tried it's air compressor or needed a jump but I like that I can plug my phone and laptop into it

Stanley Professional charger has been a great asset. I used the tire inflator. Just set the pressure wanted and turns off when it hits the pressure you set.

Awesome device. Start your car with a dead battery, charge upto 4 USB devices, bright LED lights, and air up tires. You can set the pressure, and it will air tires to exact pressurem

I have only used this once. I really like the portability & ease of use. I checked the pressure also with my other tire pressure gauge & this machine was within 1/2 lb. So much easier to use than my large air compressor with the extra long hose.

Have only used it a couple of times to start a dead battery but it worked perfectly. I use it at our cabin to charge phones and keep ATV/ UTV tires inflated.
