Now with more robust connectors for improved durability
This will allow you to charge power hungry micro USB devices such as the Raspberry Pi, Google Nexus, Asus Transformer, Blackberry Playbook or other micro USB device at high speed from a powerful charger, such as one rated at 2A / 10W.
Uses even thicker 22AWG copper cable to allow the same speed charging as our 150cm cable - has lower resistance so more power goes to your device and less is lost in the cable as heat. It follows the 'Dumb USB' specification, ie with the D+ and D- lines shorted. If you're already getting a fast charging speed then your charger follows the correct spec, and this will simply be a safe, high quality 250cm replacement charging cable.
Prevents your device going into 'data transfer' mode when connected to a computer, acting as a 'USB Condom' to prevent data theft / viruses when charging from an unknown USB socket. It works with all devices which charge from a micro USB socket including smartphones and satnavs from Samsung, HTC, Google, Sony, TomTom, etc.
Note your device will not charge faster than it was designed for - usually this is the same speed as charging from the original mains charger.
The technology in this cable is already built into our car charger (B00E72WG18) and mains charger (B0073JB4QU)
