Looking for a new charger. Nothing really wrong with my I4 just thought I should upgrade.
I only have two complaints about my I4 after almost two years of service.
1. The slider on the #2 slot gets hung up constantly. All the sliders feel cheap and crappy. This part of the design needs to be improved.
2. I can’t prove it but I think it has ruined one or two of my new Eneloops. I now only use it for LiOn cells and just use my Eneloop charger for NiMh.
What I want in an upgrade:
1. Safety. I don’t want to worry about it burning my house down when I sleep.
2. Ability to charge both NiMh and LiOn without damage.
3. It would be nice to be able to put any combination of cells in and have it charge correctly according to chemistry.
4. A digital readout would be nice but not needed
5. Under $40
6. 4 slots would be preferred but I can live with two really.
7. Gentle on my batteries. I don’t care if it takes 12 hrs to charge. I just don’t want it destroying my cells.
Nitecore I4 has been noted potential to kill nimh, such as Eneloops, youre the second person Ive read make the claim they have. HKJ also notes the potential for that.
