Larry,
I use a 300-Watt inverter I bought at Harbour Freight and a car battery.
Powering my GoTo telescope mount, DSLR camera, and laptop for 2 hours dropped
the charge about 10%.

Subject: [AZ-Observing] How to power my laptop
Can anyone guide me on what I have to buy to power my laptop in a remote
location??
The internal battery might last a couple of hours and the external battery I
bought is only good for about 3 more. Really not enough for a full evening.
I believe I need to purchase a "dry cell" battery with an inverter?? Can
anyone maybe be more specific as to what I need?? There is a Battery Plus
store close tom where I live, would they be able to help??
Thanks, Larry Irene
