I don't have the blink camera, but what I do have is a ptz, HD, wifi 'Amorom' smart camera which doesnt actually utilize the weatherproofed shape of the USB stub, but the cable does fit and power my camera just fine, and the flat cable is extremely long and flexible, so it reaches all the way around the corner, to the electrical supply outlet, which is rather far from the camera. This convenient pair of cables includes a pair of 5vDC @2A USB charger/power supply units. As long as you have a camera, don't worry about figuring out if you have the original power supply. Two amps of five volt power is plenty enough to power every single night-vision/pan-tilt-zoom/smart motion tracking/ wifi / 2way talk/ motion alarm push notification/ etc feature which your camera unit is equipped with. The flat wire feature is very cool for tucking out of the way, and maybe behind some trim boards or something like that. Keeping the power input cable out of a potential burglar's reach/access is important to maintain high-security and keep any breach/system sabotage to a minimum.
I give this product five stars for universal USB type-c appliance fit and function. ⭐⭐⭐⭐⭐
(I can even charge my cellular phone with this cord 👍)
