I got this charger from ZGEAR and I tried using it but it always stops charging my phone after a minute. Like I have to keep pressing this button on the charger to keep charging my phone.
Buy a motor and hook it up to a 3 or 4 bar linkage so that the arm can press the button for you.
The batteries inside the portable charger are too weak, either you change them ( non rechargeable battery bank ) or recharge this charger built in rechargeable battery bank. Now this portable charger has too low voltage output that phone rejected it from charging.
