A:AnswerThe unit comes with a rechargeable sealed battery pack. The pack has an LED on the outside that changes color when it is fully charged. A microUSB cable and charger are needed, both of which you'll need to provide. I let mine initially charge for about 8 hours, although 6 hours would probably have been plenty. Eufy indicates that a full charge should last about 12 months of normal use.
A:AnswerI have had NO progress getting duplicate keys. Evidently they're not standard blanks and Eufy says they do not make blanks for duplication. Without the bland, even a locksmith might not be able to make dupes, so beware - if you need more than the two keys furnished, you're sol, at least for now.
