Help me out, which charger - choice of 3???
I want/need to get a charger to charge 18650's, 14500's and RCR123's.
Ideally I'd love the best money can buy, but by bank account won't :duh2: So I've narrowed it down to 3 potential candidates, of which I'd love for you guys to tell which is the best and why, or the pro's and con's of each.
Option 1:
4Sevens Single Bay Smart Charger
This is 4Sevens own single-bay smart charger. It has a constant-current, constant-voltage (CC/CV) circuit. This means it will maintain a constant current to the battery until the terminating voltage (user selectable) is reached, then it will maintain a constant voltage; thus, the current is naturally reduced as the voltage approaches the terminating voltage.
Our charger can also be powered by USB and comes with a USB/MiniUSB power adapter!
Charger Specifications
Two user-selectable voltage settings:
3.6V / 4.2V
Two user-selectable current settings:
0.5A / 1.0A
Compatible with the following battery sizes:
14500 / 16340 (RCR123A) / 17670 / 18500 / 18650 / 26650
Primary Input Voltage: 12.0V, 1A
Secondary (USB) Input Voltage: 5.0V, 500mA

____________________________________________
I've read some less than enthusiastic comments about the Ultrafire charger, so I unless convinced I think it'll be a no. However I've not managed to find anything else out about the others, so would really appreciate some help. They are all very similar priced, I just want to buy the best for my budget (£20-30).
Thanks.
