Duracell DPP-300EP Has some limitations

I've used this to inflate the tires on my car and it works just as well as my last compressor. There's even a gauge to show what the tire pressure is as I'm inflating.

OUTLETS

I used this on a camping trip to power my vacuum via the 12V DC socket. I also used it to power my ASUS eeepc netbook via the 12V AC socket. That was no problem.

There are two 12V AC sockets, so my husband tried plugging his notebook computer in while I had my netbook in. The fan started blowing as soon as he was plugged in and eventually a loud alarm sounded. I thought it was too much for the battery to have both units plugged in. When my husband tried his notebook in without anything else connected, he got another loud alarm. He has a large, 17" notebook. It was just too much of a strain on the battery. My netbook never got the alarm by itself.

I was camping for three days and I used the battery for a few hours the first two days with my netbook. The last day, the battery read empty, but it still had enough juice to power the vacuum.

FLASHLIGHT

The flashlight uses LED lights. It's bright white light, brighter than the flashlights we had brought with us to the campground. The LED lights are arranged so that the output forms the shape of Mickey Mouse and the light is not even but rather forms rings with light and dark areas, but it was sufficient enough for me to navigate my way through darkness.

JUMPER CABLES

I am happy never to have needed these cables but I'm glad they are there. If I should even use them, I will come back to update the review.

CONCLUSION

I am happy with the performance of this product. Had I been my husband, who wanted to use it for his notebook computer, I wouldn't have been so impressed. It's a great product to keep in the trunk for emergencies. Just keep in mind that the battery does have its limitations.
