The battery capacity is sufficient for just one night, then has to be directly recharged. We have ordered 2 of them since 2 children and the problem still exists in both cases, you have to remember then more daytime charge, otherwise you have the evening (or already during nap) a problem if you are not too keen plugging the charging cable. Otherwise, the baby monitor is very good, both visually and functionally. Easy to use, with all the extras you would need. Especially nice is for example that the receiver of the night light can also turn on and off, for example, if the child cries at night because it needs to use the toilet .. The music can be switched on by the receiver on and off. It is a string with which you can attach the receiver to get it to hang around the neck. I find this very handy if, for example, or the like brings the full laundry basket from the basement and as the hands free.
