AmazingProductsClub.com presents the Battery-Free Extended Selfie Arm with Button uses a tiny coiled cable with a 3.5mm jack to plug into your phone’s headphone port for remote shutter control.  It doesn’t need a battery at all and can support up to 3.3 lb; its remote button is large and perfectly placed, and it offers a 0.1-second response time.  The smartphone’s mount screws onto the pole’s ball head and supplies thick rubber pads for protection and a no-slip grip.  The pole extends to 35″ but collapses to a tiny 8″, which is great for transport.
