Buying Guide for Portable Air Conditioner Extension Cords
Choosing the correct extension cord for your portable air conditioner involves several important factors to ensure safety and efficiency:
- Wire Gauge (AWG): Select cords with 14 gauge wire to support high current loads. Thinner wires (higher AWG numbers) can overheat and cause hazards.
- Amperage and Wattage Rating: Make sure the cord supports at least 15 amps and around 1875 watts, matching or exceeding your air conditioner’s requirements.
- Length: Choose an extension cord that is long enough to reach the outlet comfortably but not excessively long to avoid voltage drops. Typical lengths range from 6 feet to 15 feet.
- Plug Design: Flat or right-angle plugs help keep cords flush with walls, perfect for tight spaces behind appliances and furniture.
- Grounding: Always choose a grounded 3-prong cord to maintain safety from electrical faults and to protect connected appliances.
- Insulation Quality: Heavy-duty vinyl or SPT-3 insulation provides resistance against abrasion, cracking, and heat buildup during prolonged use.
- Indoor vs. Outdoor Use: Verify if the extension cord is rated for indoor use only if used inside. Outdoor cords require additional weather-resistant features.
By focusing on these aspects, you can find a reliable extension cord that safely powers your portable air conditioner, fits well in your space, and performs efficiently over time.
