Battery or mains pond fish feeder

Updated: 22 October 2026

The pond is at the bottom of the garden and the nearest socket is in the kitchen. A battery or mains pond fish feeder is a choice between fresh alkaline cells you can change yourself and a 230 V outdoor circuit an electrician has to make safe. In this amazon.co.uk set the documented units are dry-cell hoppers. Cells fail quietly. If you have no outdoor socket, stay on fresh alkaline cells and plan the change before you travel. The [pond fish feeder comparison](/hub/garden-ponds/fish-feeder-pond) holds the product table. Peter F. did not run a lab test. A qualifying purchase can earn a commission at no extra cost to you.

What this set actually runs on

Documented power in this comparison is dry cells. The Fish Mate P7000 takes four C cells. The Hozelock takes two AA cells, and the manufacturer manual treats it as battery-operated. Do not invent cell sizes the other listings do not give. CISSIYOG’s wording is indoor, so it is a weak answer at the pond edge. Two claims stay unresolved. The hygger listing is described as battery powered and also as shipping a power adapter with batteries not required. Do not call it battery-only until the live page and the box agree. Hozelock’s table line says hand-operated, while the bullets require AA cells. The manual treats it as battery-operated. UK mains results jump to Cloverleaf, JBL and FoodFlinger, which are outside this set.

Cells fail quietly, so fit them before you leave

A dead feeder does not splash. It skips meals until someone notices. On the P7000, the low-battery icon is specified for alkaline cells, not rechargeables. When it shows, replace all four C cells within 60 seconds and do not press buttons, or the programme resets. The instruction PDF says about 12 months. Closer Pets says about six to nine months. Keep both sentences, and fit new alkalines before you travel. The Hozelock manual’s test is about six weeks on alkaline AA cells at six feeds a day. The text used here does not describe a low-battery lamp. The instructions say not to use rechargeables. That six-week line is a test claim, not a date in your diary. Leave a spare pair with the person who is checking the pond.

A mains feeder needs a real outdoor socket

Choose mains only when a weatherproof outdoor socket is already there, or when an electrician will fit one. UK mains are 230 V, and the plug has to be BS 1363. Electrical Safety First, citing BS 7671 regulation 411.3.3, describes additional 30 mA RCD protection for outdoor socket-outlets and mobile equipment up to 32 A. NICEIC tells householders to use an RCD-protected weatherproof outdoor socket. IP66 in that guidance is a usual rating for the socket, not for the feeder. None of the seven listings states an IP code. Do not run a long indoor extension to the water. NICEIC warns that long leads overheat. Buried cable and a new socket are an electrician’s job. The Electrical Equipment (Safety) Regulations 2016 cover a mains adaptor. A dry-cell feeder still sits under the General Product Safety Regulations 2005. If the plug is cracked or the adaptor is hot, stop using it. Do not open the consumer unit.

Dearer units are not a patch for a bad socket

A feeder that costs more does not repair a socket you do not have. That Pond Guy lists a Cloverleaf feeder with mains and battery failover, an IP55 claim, and a price around £279.99. That claim does not transfer to Fish Mate or Hozelock, and those units are outside this comparison. Inside this set, stay on dry cells unless the socket is already right: four alkaline C cells for the P7000, or two alkaline AA cells for the Hozelock. If hygger is in the basket, wait until battery-versus-adapter is one story on the live page.

Common questions

Can I run a pond feeder with no outdoor socket?
Yes, if you stay on a dry-cell feeder and fit fresh alkaline cells before you rely on it. The P7000 takes four C cells and the Hozelock takes two AA cells. A mains adaptor without an RCD-protected outdoor socket is the wrong substitute. An indoor extension to the pond is not the plan.
What batteries does the Fish Mate P7000 take, and how long do they last?
Four alkaline C cells. The instruction PDF says about 12 months. Closer Pets says about six to nine months. Keep both sentences. When the low-battery icon appears, replace all four within 60 seconds and do not press buttons, or the settings reset. Pack spares.
Does the Hozelock warn you before the AA cells die?
The manual text used here does not describe a low-battery lamp. The maker’s test is about six weeks on alkaline AA cells at six feeds a day, and the instructions say not to use rechargeables. That line is a test claim, not a date in your diary. Fit new alkalines before a trip.
Is the hygger battery or mains?
The listing says both, and that contradiction is unresolved. One line calls it battery powered. Another says it ships a power adapter and that batteries are not required. UK reviews have described a mains plug. Do not buy it as battery-only until the live page and the box match.
Can I use an indoor extension lead to the pond?
No. NICEIC warns that long extension leads overheat, and a lead from the kitchen is not a weatherproof outdoor socket. Regulation 411.3.3, as Electrical Safety First explains it, is additional 30 mA RCD protection for outdoor sockets up to 32 A. If the garden has no such socket, stay on alkaline cells or ask an electrician.
Who fits a new garden socket?
An electrician. Buried cable and a new outdoor socket are not a feeder accessory you wire yourself, and this page does not describe how to wire one. Ask for a weatherproof socket with RCD protection on a BS 1363 circuit. A cracked plug or a hot adaptor is a reason to stop using that product.
