The Gomadic High Capacity Rechargeable Battery is a well built and well-designed battery
, and I use it heartily and happily. I hate the tiny connectors, and have resigned myself to leaving it at home and just charging the battery at night, alongside my iPhone, though I'd much rather carry it with me for convenience' sake. I don't like to feel forced to recharge the battery nightly, in the event that my iPhone requires more than a single charge in the day, and for work I always have my laptop and/or my car around, both of which could recharge any device. At least with this battery, I get to keep my iPhone slim in my pocket, and charged wherever I go.
