... and I have multiple options to keep my laptop powered during an outage.
Could you share some of them? Obviously the battery is one. There is a way to power a laptop from the car adapter. Are there other options without resorting to buying a generator for the house? Maybe something like crank flashlights/cell phone chargers, but for laptops?
I started with a Dell Latitude E430 with
extra standard batteries and an
extended flat battery that attaches to the bottom of the unit. It becomes heavy with all the extra battery power attached, but I have almost 8 hours with this setup. Dell's
power supply for this unit includes a 12 volt cigarette lighter adapter that plugs into the side of the power supply.
I have two
12v 7.2ah SLA batteries carried in a
nylon bag I purchased from Jaycar out of Australia that has a built in socket. This can plug into the Dell power supply for several more hours of service. SLA batteries are cheap, have a long service life, low self-discharge, and are easy to charge with the right equipment (
low amperage float charger).
Finally, I purchased a couple of
Goal Zero rechargeable battery packs that can be charged with a
solar panel or by normal AC power.
For extended power outages, I plan to recharge any of these units during the daytime hours with a
Honda 4kw generator. Even through our worst hurricanes in 2004, I never got past the second SLA battery for normal usage. The beauty of the
SLA battery is that you can also use them to charge cell phones and other devices that have a 12v vehicle charger.
If anyone is interested in the details, I can edit this post to add links to where some of this stuff can be purchased.
