A day and a half????? LORDY LORDY!!! lol Thanks for the info. On my way to youtube now and peek at them ...
Both the E-Power and the kGo will give you the long battery life your looking for. kGo batts are 1100mah and E-Power batts are 1050mah. So both will most likely last you at least a day.
Personally I like the E-Power but the kGo is also a great PV. Like hairball said, non-proprietary batteries are much cheaper to replace than proprietary batts. E-Power batteries cost $4 compared to kGo batts that are about $18. Ive never used the Indulgence but that would also be a good non-proprietary battery option. It looks like a really solid PV, and like Hairball said, an all mechanical PV is always nice
The biggest thing I dont like about the kGo/eGos is that the tube, battery, and switch are all one piece. If you need a new battery or you blow a switch you have to replace the whole unit. With the E-Power their all seperate pieces. If you need a new battery, you can buy just a battery. If your switch stops working, you can buy just a switch and continue using your existing tube and battery. It def really helps keep costs down.
I also like that it is easier to carry a spare battery with the E-Power than the kGo. With a non-proprietary PV like the E-Power or Indulgence, its easy to just throw an extra battery in your pocket. The E-Power battery is about the size of a AA but alittle longer. For a proprietary battery PV, to carry a spare battery you basically have to carry a second PV. Its not a huge deal, but for me I work in a financial firm and are always running around to different places. Its much easier to carry a small battery for a spare in my suit pocket than to carry a second PV. For you, it might not be an issue though
