You won’t be caught with a dying cell phone battery with this. It’s a useful addition to your flashlight collection. This has a battery holder for a 18650 Lithium battery, and converts the battery to 5V at up to 1 amp, out to a USB jack. You can plug your cell phone cable into this, or use it as a flashlight with the LED ‘head’ that comes with the adapter.
A HDMI switch, which seems to be the trend nowadays with HDMI everywhere.
