Question about Raspberry Pi 2, model B

I would suggest xqisit universal USB charger & Roline Micro USB cable.

The power cable is not part of the standard delivery of the Raspberry Pi 2 Model B. I strongly recommend a good quality adapter with 2 A at 5V which guarantees that the required input voltage is always available. I had endless problems with a cheap 1.2 A/5V adapter I bought in a department store (from network crashes to defective µSD cards) until I replaced the adapter with a SAMSUNG Travel Adapter ETA-U90EBE with 2.0A at 5V. I'm not sure if it's the same adapter, but the SAMSUNG ETA-U90 with item number 434009 should fit well in any case.

The regular scope of delivery of the Raspberry Pi only includes the computer itself without the power cable. However, you can use any micro-USB cable to supply power (Model B requires 700mA at 5V).
