Yellow Port was created to solve the problem of on-the- go charging for smartphone users all over the world. Our phones were constantly running low on power, and we had been frustrated by the existing solutions out there. We got tired of carrying our charging cords in our pants pocket and searching for a wall outlet, or being tethered to a charging pole just to squeeze a little more juice into our phone batteries when we could. We also didn’t want to buy expensive external battery packs that we would have had to remember to charge and carry with us.
