I took two chargers, one that had the right tip and one that had the right DC voltage, that were cord compatible, and Frankenstein'd them together. It cost me nothing more than a little solder and time. Since the new one's cord is thicker and the transformer/charger is beefier, it is a better one that the stock charger. I use it all the time to charge, and I have the one that came with my PDN in a little neoprene case to take on the go. If you have the supply of extra chargers like I do (about 40 different ones from just about every sort of device you can image), then it can be fun and save a little dough in the process. Be sure to check the voltage, though. Some 12V chargers output as much as 18V. I just used my meter to be sure I wasn't going to fry the PDN. It will probably take more than 16V, but I didn't want to risk it.
