If you provide details of your power requirements, we will make certain you have power available at your exhibit area. One 5 amp circuit (0-500 watts, 110V) can be provided for free. You will be charged an additional fee based on your power requirements over 5 amps. Please bring your own extension cords, surge protectors and/or power strips for power distribution at your exhibit. Last minute power requests cannot be guaranteed.

Understanding your power usage is important: To ensure you have adequate power onsite, it’s essential we know in advance the specific amount you need. To find the total amperage you require, find the amperage listed on the back of each piece of equipment you plan to bring onsite. Then, add up the amps of each piece of equipment. Please check your equipment, and don’t guess. We thank you in advance. The power requirements may be listed on the back of the item in question, on the converter box, or on the electrical plug itself.

Voltage: In North America, normal house and building power is 110 volts.

Amperage: After you determine the voltage you require (see above), we need to know how many amps you will be using at that voltage. If an item only lists watts and not amps, you can quickly convert watts to amps by dividing the watts by volts (Watts / Volts = Amps.)

Examples: A 500-watt light bulb requires approximately a 4.5A (A=amps) on a 110V (normal US) circuit: 500/110= 4.5. Here’s a list of average amperage for common Maker Faire items: Laptop ~2A, Sewing Machine ~0.6A, Lights ~0.3A-2A, 3D Printer ~10-20A, Arduino ~0.1A, cellphones/tablets ~0.5A-2A.
