High School Determining whether an external battery can deliver enough power
Ok, I'll keep that in mind. This battery http://www.batterygeek.net/Batterygeek-100-Hr-iPhone-iPod-iPad-Battery-Pack-p/geekpod_110_.htm offers some specs if you scroll down a bit and click the 'Technical specs' tab. The 5.4 Ah battery - as you noticed as well - doesn't offer much information. -

No. The charging cable plugs into a standard USB socket. The external batteries also come with USB sockets, so that's what I will be using. -

High School Determining whether an external battery can deliver enough power

Car Air Conditioning: Energy Usage & Benefits
Sorry for reviving this old thread, but what exactly is the conclusion to this discussion? I'm very interested, as I'm soon going on a long road trip in a rented Chevrolet Aveo which, I presume, utilizes a simple A/C on/off switch with no thermostat. Will we be best off cycling the switch or...- ZrednaZ
