Default Charger EP800 query

I recently sent my handset off for repair and they forgot to send my charger back with the new handset. They've now sent me a new one, it's arrived today and is an Ep800 instead of the EP880 included with the phone from new. Is this a good thing or a bad thing? The 800 seems a newer design but puts out like half the amps the 880 puts out.

Sony are beginning to annoy me...
If it's broke, use a hammer. If that fails, you're not using a big enough hammer.
