Most cameras make use of rechargeable lithium-ion batteries. They come supplied with an original battery charger, but you might just as well use a DSTE charger, which is more affordable.
You will not notice any difference with an original charger, because DSTE battery chargers are known to be very reliable with a great price/quality ratio. Moreover, they are very compact and you can even connect it with a 12V car charger cable. Very convenient for your holiday!
