A:AnswerYes, I was able to have to have 2 spares for the very long tours during a 2o cruise where I took over 1200 photos! Additionally, easier to use without constantly plugging in the charging wire into the phone
A:AnswerNo, in order to get a charger for your Nikon D3300 you would need to purchase the RF-DSLR-500N digipower-re-fuel charger.
The RF-TC-55N is only for smaller cameras such as point and shoot.
