Cable reel or extension lead: which shape outdoors

Updated: 23 October 2026

You are choosing between a drum you can walk down the garden and a 10 m bar with three sockets, and both titles say outdoor. A cable reel or extension lead is not a small difference in this set. Six of the seven listings are reels. One is a straight lead whose own reviews quote indoor-only paperwork. You should finish knowing which shape you are buying, and which weather words are actually printed. The rows are the [outdoor extension lead comparison](/hub/sockets-and-extension-leads/outdoor-extension-lead). The Products Compared editorial team compared these amazon.co.uk listings on 21 October 2026. It is not a lab test. A qualifying purchase can earn a commission at no extra cost to you.

Two shapes in this set

The reels run from 10 m to 30 m: the £19.99 four-socket SLx, the £16.95 reel titled IONOS, the £19.95 15 m Status, the £34.99 20 m SLx, the £25.75 25 m Status, and the £44.99 30 m SLx. Each of those six claims a thermal cut-out. The straight lead is only the Etykir bar, at £19.99. It is 10 m, three sockets, one switch for the block, Type G, with 13 A and 3,250 W claimed. There is no drum, so there is no wound-current figure and no thermal cut-out described. It has 4.5 from 70 reviews. A reel stores length and then asks you to unwind it. A bar gives you 10 m and then stops. If 10 m does not reach, the bar is the wrong object. The check order is the outdoor extension lead buying guide.

What you take on with a reel

A reel is the right shape when the job is longer than a short trailing lead and you will pull the cable off before the tool starts. Electrical Safety First’s garden advice asks for an outdoor-suitable lead, a full unwind, and a thermal cut-out. London Fire Brigade warns that a drum left coiled can overheat. Five of the six reels print no IP code. Weatherproof, outdoor and garden in a title are not a code. The exception is the SLx 90025PI, 20 m, two covered sockets, IP54 printed, £34.99 in the snapshot, 4.6 from 4,160 reviews on that file. The bullets say splashproof. The title says waterproof. SLx’s IP guide says the second digit 4 means splashing, and that the lid has to be shut as instructed. Reviewers praise those covers in the rain and also say the clips are hard to close.

What the straight lead prints

The Etykir bar is the right shape when you want about 10 m, three sockets, and a single switch, and when the run stays where the paperwork allows. Reviewers say 10 m reaches the end of a garden when the lead stays out of standing wet. The switch cuts all three sockets together. A reviewer notes that a front-facing switch can be knocked off if you step on it, so the bar does not belong on a path. The listing claims surge protection and does not say how many joules. A surge claim is not an IP rating. Two mounting holes let you screw the bar down. Screwing it to a shed wall does not turn it into an outdoor socket, and it does not add a 30 mA RCD. The plug fields say Type G. One reviewer sees a CE stamp and no British Standard kite mark.

Outdoor in the title, indoor in the reviews

Several UK reviews of the Etykir lead say the instructions or the packaging say indoor use only, or not for damp or wet conditions. The title still says outdoor. No IP code is printed to settle the argument. Maplin’s safety post says that if no IP rating is stated you should assume indoor use. That matches the paperwork those reviewers quote. Maplin also suggests IP65, a shop opinion this page does not adopt as a rule. Only the 20 m SLx prints IP54, and that is splash at covered sockets, not a soaked lawn. If you need the bar indoors, or under a proper cover, the 10 m length and the three sockets are the reason to pick it, at £19.99. If you need the sockets outside in the wet, refuse the outdoor word on the Etykir title. Which listing matches a job is the best outdoor extension lead page.

Common questions

When is a reel the right shape?
When you need more than about 10 m, or you want the spare cable on a drum you will fully unwind before the tool starts. The six reels here run from 10 m to 30 m and claim a thermal cut-out. You take on the unwind rule, the rewind complaints in the reviews, and, on five of them, the lack of an IP code. The 20 m SLx is the one that prints IP54.
When is a straight 10 m lead enough?
When the socket is within 10 m of the job, you want three outlets and one switch, and you will follow the indoor or not-for-damp paperwork reviewers quote. The Etykir bar has no drum and no thermal cut-out in the listing. It is the wrong buy if the flowerbed is 15 m away, because you should not join a second lead on the end.
Does the Etykir lead have a thermal cut-out?
Not in the listing. Surge protection is claimed instead, with no joule figure. The six reels are the products that claim a thermal cut-out. That device responds to heat. It is not a 30 mA RCD, and the straight lead does not include an RCD either.
Why do reviews say indoor use if the title says outdoor?
Because several UK reviewers say the instructions or the box say indoor use only, or not for damp or wet conditions, while the amazon.co.uk title says outdoor. No IP code is printed on that ASIN to override the paperwork. When the title and the paper disagree, the paper in the box is the instruction you can read with the product in your hand.
Does a surge claim make it suitable for rain?
No. Surge protection, even when a joule rating is printed, is about spikes on the supply. This listing does not print joules at all. Rain and splash are an IP question. The Etykir lead has no IP code. The reel that prints one is the 20 m SLx at IP54, and that code is splash, not immersion.
