Head over to Walmart where you can grab the ZeroLemon JuiceStick External Battery Portable Charger for just $9.99! Plus, it will ship free. This could make a great Mother’s or Father’s Day gift. I have a portable charger and I use it all the time. It lives in my purse during the day so I know I can always have a full battery. Then when I go to bed I re-charge it.
