decided on a laser but now what charger to get ??

Okay so unfortunately I can't post the exact link for you guys because I'm on my phone but the laser I've decided to purchase is the 50mW Transformable Green Laser/Adjustable/Burning for $46.44 off of O-like.com. If you go to the website and then click on "green lasers" on the left hand side it should be the last one on the list all the way at the bottom of the page. Two types of batteries, 18650 Lithium and CR123A Lithium, can be used for this laser which can allow it to be shorter or longer depending on preference. But I'm a bit confused. Does it need TWO CR123A batteries to function or only one? I know it only needs one 18650 Lithium battery but I'm not too sure about the CR123A batteries. It comes with one CR123A battery but no charger so I need to purchase a charger as well so my next question is should I get a charger for the 18650 battery or the CR123A battery. Both chargers come with one battery that matches the charger. Which battery will make the laser perform better? Or are they both the same?

The laser takes either one cr123a or one 18650 if you use the extension tube they provide.

The 18650 will provide longer run times, but aside from that there is really no difference. Obviously since the 18650 is much longer, the laser is much more compact when using the cr123a.

Look for a charger that is capable of handling any 3.7v battery... that way you won't have to get another one next time.

So Infinitus, which one would you chose if you had to pick one? If I get the charger used for the CR123A I'll have 2 batteries for the laser but I won't be able to use the extension tube to make the laser bigger if I want it bigger. Can I use two CR123A's with the extension tube? Or would that not work..

No you absolutely can't use two cr123a batteries with that laser...

If size is not really a concern for you, I would definitely suggest the 18650 battery.

You can also buy good batteries and a good charger from here:

Okay I'll take your advice and go with the 18650 and just get a charger for it. It's gunna kinda suck having the CR123A that it comes with and it basically being worthless but maybe I'll be able to use it in the future. Thanks for the advice.

Contact o-like and see if they can send you a 18650 battery... won't be as good as Larry's but you might as well.

I'd get this charger if I didn't have three separate ones already.

I still may get one to reduce the clutter. You can get it a lot cheaper from places like DX if you're willing to wait a couple weeks for shipping from China.
