Trouble with TP charger, question about hyperion charger

[JThiessen]

I think on the hyperions it will flash the power supply input - haven't looked at mine, but I've just now got my power supplies wired up to run my new Duo - I have to update the software on it also. Anyway - double check your power supply with a volt meter to make sure that its putting out enough power. I also wonder if it will limit it to 2C if it only see's 12V? May want to check your manual.

I've no idea on the other charger - never used that brand. Sounds like a dud to me. I'd take it back to the LHS he bought it at. I'm assuming he tried a couple different outlets (maybe he picked a bad one to plug it into??).
