Yesterday evening the power at my office went out and was off for about 8 hours. My APC UPS lasted for about 50 minutes of that. I'm thinking about buying a Duracell emergency power source. http://www.amazon.com/Duracell-DRPP600-Powerpack-Starter-Emergency/dp/B009YR00MI/ref=pd_sim_auto_5#productDetails The instructions for the APC UPS say to only plug it directly into a wall socket. I'm wondering if I could plug the Duracell thing into the APC UPS and then plug my computer stuff to that. The alternative is to use them one at a time and manually switch from the APC UPS to the Duracell thing when the APC UPS is almost dead. I was around last evening so it wouldn't have been a problem, but if chaining them would work, it wouldn't matter if I wasn't around. I'm also thinking about bicycle generator systems: http://www.pedalpowergenerator.com/ I've seen Frank and Amelia use something like that at the State Fair.

I think prices will increase by 6.5% after that. -------------- next part -------------- An HTML attachment was scrubbed...
