This is the best of the many products our family has purchased from Brookstone over many years. You can have lighting, run electrical appliances, charge portable electronics including laptops and cell phones and even run medical equipment during a power outage.

Dead battery? Not a problem - this device can save you from a random stranger or long wait for roadside assistance because of the included jumper cables.

We have purchased one for our use and four others as gifts and everyone has told us about some situation where this device has been incredibly helpful to them!!!!

Don't give it another thought. Buy it!!

Worked great for for the first year or so. Then, my power went out. Wanted to use the light but it wouldn't work. Tried the hand crank to charge it up. I cranked it for around a half an hour. Nothing. Still reads zero on the display. After the power came back on, I plugged it in to try and recharge it. It displayed a 100% charge for about 15 seconds and then it said recharge on the display. It does not keep charging. So now, after a little over a year, it's useless. Past the warranty period. Think twice before you spend over $200 for this device.

        Comments about Portable Power Supply:

        I purchased this a while ago, at least two years, and wanted to use it in case the power went out during the recent (January 2015) blizzard. I tried to charge the unit and it would not charge. Fortunately I never lost power; I only lost the money I spent on this product. Avoid at all costs

        This was the WORST experience I've ever had with a product, and I tell you, don't buy it, I know you might be exited or something, just find another one.
        Mine broke after ONE DAY of use, the output AC would output a low voltage which is not enough for ANY uses, I WOULD RECOMEND YOU NOT TO BUY THIS!!!

            Comments about Portable Power Supply:

            The device has an opening for "Solar In", but no one at Brookstone knows anything about it. Brookstone can NOT tell me or anyone where to get the proper solar panel for the device. The customer service dept doesn't even know what TYPE of panel to get (5 watts?). If this device has a solar input feature, it's not doing me any good.

                        This product was great, kept charging it, and used it once for a few hours. I stored it properly, but now, 5 weeks after the 1 year purchase date, it doesn't work at all. This is terrible. Hundreds of dollars down the drain. Don't buy this if you plan on using it after a year. I'm going to look into other produts.

                          Bought this as a backup if the power goes out. I never got a chance to use it, not once. Kept it maintained by charging it every several months. Today it would not take a charge, battery is shot evidently. I would have been much further ahead to buy a cheap gas generator and store some no ethanol gas and put some additive like gas stablizer in it. The gas would have stayed usable longer than the battery, and I would have had much more reliable power.
                          This is the first thing I've ever bought from Brookstone and I'm sure it will be the last. You know what they say about first impressions.
