# Set-Up (Charging Station)

***

## Step 1: Gather Equipment

Acquire smartphones—a mix of any Android or iPhones models can be used with a single Charging Station. Although iPhones can certainly be used with the Cellhasher Charging Station, many activities related to Cellhasher require Androids. Furthermore, Cellhasher Control does not support iPhones.

## Step 2: Prepare Phones

Head to [enabling-usb-and-wireless-debugging.md](/docs/additional-docs/enabling-usb-and-wireless-debugging.md) and complete this process for your phones.

## Step 3: Adjust Cellhasher Input Voltage

Determine if the circuit associated to the outlet you plan to connect to is rated for 120V or 240V. This is important to confirm.

Every Cellhasher has an adjustable power supply unit (PSU) that supports either 120V or 240V. You will want to confirm its set to your corresponding circuit. To toggle between these, locate the sticker next to the red switch inside the PSU. Use a long, rigid tool (such as a screw driver) and fully move the slider according to your circuit, if it is not already.

## Step 4: Insert Phones

Using the USB cables provided, connect the phones and slide into their slots. Once complete, power the Cellhasher on.
