Hi guys and gals, Now and then it is very annoying that I only have one PF charging adapter, quite some other perfectly compatible adapters that just won't fir the charger jack, etc. etc. I found a very decent solution to charge our LEGO Train PF LiPo's: The infamous Limor Fried aka Lady Ada sells them for only 2.5$ The battery is charging (red LED is blinking), but there is about 50% chance when one takes a picture that the LED is of and I was too lazy to take another picture with the LED on. Here is an example adapter that I had lying around somewhere. 2.0A 9V DC seems to be working very well. Make sure the adapter can deliver enough current and is also not exceeding 10V (according to the LEGO PF LiPo specs). Make sure that the middle pin is the + and the edge is the - (which is the case for most standard adapters). Hope this is something more people will appreciate. Note: the LiPo is very well protected (my students have been very mean to it and it still works very well), but use this at your own risk of course, if you take the precautions I mentioned you should be fine. If the adapter cannot draw enough current it might overheat though! Also note that the old 9V adapters (often 10V are not DC but AC (~)
