Wall Charger For Clip Zip

I just purchased a Xuma Model IP-AC201, dual USb wall charger from B&H.  It says it has 2.1A , Universal 100 to 240 V AC.  Reviews said it is ok to use with Zip Clip.  Just want to make sure it is ok and won’t blow up my Zip Clip.  Also, is it ok to charge my Zip Clip for the first time using a wall charger?  Thanks.
