The typical one which is the one you see all over ebay is adequate for 98% of current batteries in the market including, galaxy S S2 S3,S5, Note 1,Note 2 Note 3, LG G1 G2, G3, Motorola Phones, Droid Phones, HTC phones,Etc.
The XL one is good for even the biggest batteries out there, as of now we have identified only 2 phone batteries that don’t fit in the standard size one. Galaxy S4 and Samsung Galaxy Mega 6.3. If you plan on upgrading to one of the giant phones in the future, this could be a good charger for you.
