1 / 7Restmo O-ECC-3 Outdoor Electrical Box, IP54, Red
Restmo O-ECC-3 is an IP54-rated outdoor electrical connection box intended to shelter plugs, extension leads and other cord connections from water and dust. Its listed dimensions suit buyers seeking space for larger plugs or a power strip, though the listing gives two different size descriptions.

- Four clips, a top lid and rubber gaskets are cited as part of the IP54 weatherproof design.

Pros and cons
Pros
- Multiple cable entry points offer flexibility for routing several connections.
- The listing describes a lid, clips and gaskets, with cable seals specified for cord, braided cable and flat wire.
- Wall-mounting holes provide an installation option beyond placing the box on a surface.
Cons
- The stated IP54 rating is a weather-protection claim, not a claim of complete waterproofing.

What to know before buying
Listing details to confirm
The listing gives conflicting size information: its dimensions table says 12.7D x 21.6W x 12.7H centimetres, while feature text says 12.5 x 8.5 x 5 inch. Its title also calls the box extra large, but the stated dimensions differ. Confirm which dimensions apply to the selected listing. The explicit contents list names a Waterproof Electrical Box, while a separate highlight mentions an outdoor outlet cover, plug, timer, power strip and holiday-light decoration without confirming those items are included. The text explicitly says the power strip is not included.

Customer feedback reports favourable impressions of the box's build, sealing, size for bulky plugs and Christmas lights, and straightforward installation. Those reported experiences are relevant to its six cable ports and stated use for larger connections, but they do not establish performance for every setup. The overall rating distribution is mostly favourable, with a smaller share of low ratings, and does not explain the reasons behind them.
Positive themes
- Customers describe the box as sturdy and functional, and praise the seals, lid closure, size and ease of installation.
