This vibrator charges a bit weird, and it took me awhile to find it out. Basically, you have to pull the silver end off and you must plug a USB cable into the port there. It doesn’t take a massively long amount of time to charge (even though I usually charge my vibes for hours while I’m out or busy), but the battery life is amazing. I bought this vibrator months ago, and charged it then for about 4-6 hours. Since then, it hasn’t died once! Super good battery and lasts awhile. The small size makes it easier to store and transport too. Would recommend.
