First of all, this is a request for a *recommendation*, not a request for someone to do Google searches for me.
- - - I need a charger for AA, AAA, and 9v batteries. Four of the AA or AAA at a time is OK.
I see very few that support all these batteries (Maha makes a separate charger for 9v). Of those that do, not all use delta-V termination (or don't specify).
Of those remaining that qualify, I've not heard of the manufacturers ("Powerlzer"? -- that's not a misspelling), or Chinese no-name ones:
The Tenergy TN190 is the only one I've seen:
Does anybody know of such combo chargers? Can recommend one?
Thanks, Dave
