I guess it works? The problem is that I ordered an RC45W, as this item is advertised, but received an RC45 and therefore my battery will not fit in it. It is a 2-piece model...the separate cord is required to plug it into the wall. The "packaging", if you want to call some bubble wrap packaging, has a sticker that says RC45W but the unit itself says RC45. Additionally, I ordered it because it was to be fulfilled by Amazon through a 3rd party merchant. When I went to return it, I discovered that the seller on the page that I ordered it from was not the same seller as on my invoice and there was a snag in the automated return policy. I will give Amazon credit for straightening it out but the entire thing was a hassle nd ann annoyance. Buyer beware if you are using a Fuji NP-50 battery and need a RC45W charger.
