I am looking to get a guardian laser and a pocket laser from San wu. Is the battery charger universal for the different types of batteries?
 





As long as it's a 3.7V li-ion battery and it fits then it should be universal, just make sure you insert it the right way and don't leave it too long unattended. I recommend investing in a smart charger for different types of li-ion batteries like this. You can charge up to 4 batteries of different types at once and track their charging plus built in overheat protection

Is there one with a single or a double for a cheaper price? I’m kinda on a tight budget

Don't have enough info to help then, sorry. Usually the negative side goes on the metal contact that slides up and down though. If it's a low quality charger, putting the battery in wrong could be bad
 
A bit late to the party, but I use Nitecore i2 charger. Pretty decent for the price (equivalent to $11).

It can automatically detect the type & capacity of the battery and then use the correct charging settings. (There is a way to manually change the settings but I never need to do that)

I just ordered one from Amazon I don’t know what brand. It is a universal charger and has 4 slots for like 9 or ten bucks
