Best for a smart plug with monitoring in Best energy monitors

The best-selling energy plug on Amazon UK, and a sensible pick if you want the reading on your phone.

LookInto Winner in Best smart plugs

The chart leader by a distance, and the one most people end up with. Setup needs no hub and the body is small enough to leave the socket next to it usable, which is more than several rivals manage.

The catch: this listing cannot agree with itself on how much it can carry. The Amazon spec table says 2,860W at 220V, the description on the same page says 2,990W, and TP-Link's own site says 2,990W. Go with 2,990W.

Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
