Buying Guide for Power Strips Compatible with Air Conditioners

When selecting a power strip for your air conditioner, the following factors are critical to ensure safety and performance:

Power Capacity and Amperage

Air conditioners typically require power strips that support at least 15 amps and 1875 watts. For larger or commercial units, options supporting 20 amps and up to 4400 watts may be necessary. Always verify the air conditioner’s wattage rating before purchase.

Surge Protection Rating (Joules)

A higher joule rating indicates better protection against power surges. For air conditioners and sensitive HVAC devices, minimal 1000 joules is recommended, but 2700 joules or more provides superior surge absorption.

Durability and Construction

Metal-cased power strips with industrial-grade components and heavy gauge extension cords provide long-term durability. Aluminum housings resist wear, and 12-14 gauge cords minimize heat buildup during extended use.

Outlet Spacing and Number

Air conditioner plugs can be bulky. Choose power strips with wide spaced outlets to accommodate the AC and other devices simultaneously. Individual outlet switches can offer convenient control and energy savings.

Additional Features

  • USB Ports: Useful for charging accessories but not essential for AC operation.
  • Mounting Options: Wall mountable strips keep setups organized and safe.
  • Compressor Protection Delay: Some surge protectors include a delay for compressor restart to prevent damage.

Extension Cord Considerations

If the power outlet is distant, a heavy-duty extension cord rated for your AC’s amperage and wattage is required. UL certification ensures safety. Keep extension length minimal to avoid voltage drops.

By prioritizing these features and selecting an appropriately rated power strip or extension cord, you can protect your air conditioner, maintain electrical safety, and ensure reliable operation.
