The Energy 16 one - £80 odd
"The Ansmann desktop charger can charge 1-12 AAA or AA cells; or 1-6 C or D cells in addition to 1-4pcs 9V / PP3 cells. Can charge both NiMH and NiCd rechargeable cells. Auto-diagnosis of the inserted cells with automatic start of a refreshing process if required. Damaged cells will be detected and discharged before fast charging. Ultra fast charging, typically 2 hours for 9V / PP3, 2 hours for AA 1800. Minus delta V charging. Switch mode power supply for worldwide use. 3 year warranty. This is designed for the more professional user."
So far it seems:
To get fast charging of 1800 NiMh's you loose the ability to do PP3's, but you can get car chargers included - Uniross do one too with 4 1700's, 12v adapter, 2hr charge and it's £35.
Slow charging is OK, you can then do PP3's but you loose the car charger.
decisions, decisions.
Plus, with some of the prices I am starting to wonder about the economics...........
