I Like That There Is The Option To Charge 3 Devices At A Time. With That Said, The Life Of The Battery Is Spectacular. I’ve Gotten 2 Full Charges For My Phone Without Issue. It’s Convenient To Have The Outlet Plug Instead Of (Another) Usb-Cable Charging System. The Slim Size Makes It Very Portable, You Can Take It Wherever You Go Just By Slipping It Into Your Bag. I Have Traveled With This Charger A Few Times Now And It Really Helps. I Won’t Suffer A Dead Phone While I Don’t Know Where To Find A Electric Station. It Works Well, And I Don’t Have A Complaint Have It. You Don’t Need Cables For This One, Comes With An Iphone Charger, C Type, And Mini Cord Plus Ports For Others. It’s Thin – But A Little Thicker Than Your Smartphone. You Can Hook Up With A Cable To Recharge The Battery Or Flip Out A Regular Plug-In – Which Is Super Handy. I Put It In My Backpack For Travel. So Far, So Good, I Shared My Personal User Experience There, Hoping Useful To You.
