New battery charger

One issue i have had is charging up and getting batteries for the panasonic HC-X1500. Panasonic want nearly £250 for a charger for this unit or just use the power block and plug into camcorder. How on earth can they justify that price beats me. I have been using a third party one I already had with plates that fitted but ok for home use but a bit of a lump for travelling. Well took some searching but found more or less exactly the same thing but powered via a USB port instead. Cost? £12 including VAT and p/p. Smaller and lighter from China I have batteries on charge with it at the moment and it charges 2 batteries at the same time.
Panasonic also do a ripoff mentioned in another thread on their batteries
