Bests & Worsts Reviews from Amazon

Initial Review - Mar 2013 - This is for the internal components of the Powerpack and not its performance or durbility. I have added few pictures to the product pictures showing the inside components of the Powerpack. I have also scanned the user manual for the runtime on AC and DC source of the powerpack and have added to the product pictures. My review is only to provide my feedback from technical aspect to help the buyers like me either to be at a comfort level to repair if they have a broken powerpack or for people who needs to understand the serviceability aspect of it. I purchased it recently and tested it only once. I ran a pedestal fan around 100 Watts continuously for 6 to 7 Hrs. I am guessing this should give a very decent 8 Hrs. for a laptop or small 12Volt or 5Volt gadgets. I was looking for a power source mainly for picnic and camping purposes. I narrowed down on this Powerpack after doing lot of research, read reviews on several powerpacks. This one is far the best by looks wise and by capacity, it has 26AH battery, all others pretty much had far lesser capacity battery (as per specs) and most of them have compressor and jump cables attached to them, which tells me the battery is very small by size and capacity. I don't need jumper cables and compressor attached to this so I purchased this one. If you need just the power source with additional capability to jump start this is the one undoubtedly from the larger battery capacity. 1. This device has a 12v 26 AH Maintenance free Lead acid battery, roughly the size of a golf cart battery or maybe a wheel chair battery. I am sure you can replace it if it goes bad, it is not a odd sized, non-user serviceable battery like Apples iphone/ipad or battery :). It is like a mini car battery so don't expect it jump start a eight cylinder vehicle or run your refrigerator. 2. It has power inverter in a enclosure probably around 800 to 1000 watts like the one we find in pep boys or Auto zone. It has other components and connectors separately modularised so it is easy to service and replace. 3. On the overall it is pretty easy to repair or replace parts and don't have to depend on Duracell. It is definitely a good device since battery can be replaced if required replacement of inverter. 4. Opening it is little tricky with two level cover screws to be removed. The orange body shell is like a clam shell with screws around the body and four screws at the bottom of the rubber feet. Once you remove orange color body shell the actual black color casing is held with normal star headed screws. Once you unscrew the case, it opens to the back cover from the USB port side of the device. Please note since this is sealed lead acid battery you can put it on its side and will not damage the battery. I will write performance review after using it for few months.
