One stop shopping for batteries.
I use digital cameras and laptops on a regular basis. I used my dell laptop as a GPS monitor which sat on top of a mini laptop desk on the passenger side of my car. I used the car lighter with an AC adapter to keep my laptop powered for the long journey across Canada. This was a great solution in terms of keeping connected and not getting lost, but overtime my laptop battery was worn out from a lot of power on/off situations.
Batteries of every kind can be found on this site for all your digital needs and beyond. I was pleasantly surprised to see they also sell adapter replacements for my particular model (a dell inspiron 1100). If you’re also a regular digital camera user, consider their line up of rechargeable batteries for your brand. Not only is it cheaper in the long run, you’re not generating more trash for the landfill.
