Safe Charging Amperage For Pegasus Mod.

Hi all. I am currently using a Pegasus 70W box mod with a SONY VTC4 battery. I currently use my USB port in my laptop for charging.

Would it be safe to use my SONY Xperia's charger with a 5VDC 1500mA output?
Also, I have other chargers (some up to and possibly beyond 2000mA), would these be safe?
