A:AnswerHi Judi,
You do not have to buy a charger.
But there is a wire that comes with the camera that will charge the battery while its in the camera.
Myself, i bought an extra battery & a separate charger that I plug into my power strip.
If you have any more questions feel free to ask.
A:AnswerThe whole camera will be really cold!! So when you get the camera let it sit til it warms up to room temperature. I wouldn't charge a battery that's really cold. Make sure that battery is is room temp or close to it. Not ice cold to the touch.
Myself I wouldn't charge a cold battery.
A:AnswerGenerally just the item with all parts and accessories and your receipt! They can look it up if you are a rewards member and/or if you used a debit or credit card. Just have to bring the card in physically to swipe through to pull up your receipt. If you are a rewards member, just give them your phone number and it can be looked up. As long as that info was put on the original receipt. Item can be opened. If you tried it and didn't like it, No problem. Just make sure it is still in good condition and within the return period which is the least 15 days (depending on your rewards membership) Some members get an extended period of 45 days.
A:Answeryour decision to want to hold and heft it is a good one. I did that, and found it was larger and heavier enough, and more awkward enough, for me to stick with the rx10 ii.
