| Yup, most modern chargers, Pentax included, do 110-220 volts no problem, so you don't need a step down converter like in the old days. Check your charger by looking at the input voltage. IIRC, the Philippines is 2 round pins so you need an adaptor to go from the flat US-style blades to the 2 pins. Radio Shack has that kind of stuff.
An extra battery is nice but not necessary IMO with the K20d. You've got to take a lot of photos in a day to kill the battery. The only benefit is if you happen to forget to charge your battery one night, then the spare is handy. I do a lot of motorcycle travel, so I'm also looking to shave ounces.
What I'd really like for traveling is an extra-short cord for the charger. One or two feet would be all you need for most hotel rooms. If anyone knew that I'd be eternally grateful. |
