A trusted brand and well built power bank
1 of 1 found this helpful This is my third power bank made by Anker. I trust their products and purchased several other products (Tripod, Bluetooth speaker etc.).
One of my Anker power bank was damaged because a faulty USB cable had an internal short circuit. This damage was NOT caused by Anker product.
I opened the enclosure of this damaged power bank and found out that Anker used quality batteries made by Sanyo (Panasonic). I could reuse these 18650 Li-ion batteries for some other purposes.
Anker power bank is a good quality product.

Low cost Endoscope with low image quality
After receiving this low cost Android Endoscope, I first tried to connect it to an android tablet. The app comes with this device could not recognize this Endoscope. Then I tried another android mobile phone, it was still not working. I figured out that in order to use this Endoscope, the android device must support using an external USB camera. I finally find a Samsung phone that can recognize this Endoscope. Please remember, not all android devices support this Endoscope.
The image quality was very poor. The major problem was that the focusing distance for the build-in camera must be more than 4 cm. For example, when inspecting the inside of a water pipe, it is impossible to keep the camera focus correctly. If a distance between pipe wall and camera is less than 4 cm, you get blurry image. If the distance is large than 4 cm, it is hard to see anything because the build-in LED light is too weak and the image is too dark.
