Reolink PSU-5V2Ax 5V/2A Power Adapter (UK 3-Pin)｜For Indoor IP Cameras

5V 2A｜UK 3-Pin｜Indoor IP Cameras｜Genuine-Spec Replacement

Product Overview

The PSU-5V2Ax is a 5V/2A power adapter for Reolink indoor IP cameras, featuring a UK 3-pin plug. Indoor cameras (such as the E1 series and E Series dome cameras) generally use 5V power, unlike outdoor cameras, which use 12V. Using them interchangeably may immediately burn out the camera.

The specifications on this page are sourced from the **official product summary provided by the distributor**: UK 3-pin plug and 5V 2A, compatible with Reolink indoor IP cameras. The official summary does not specify the cable length or dc plug dimensions, so we will not make assumptions.

Power adapter failures are uncommon for indoor cameras, but when moving house, rewiring, or replacing a lost original adapter, using a correctly rated genuine power adapter is much more reliable than buying a “universal 5V” adapter from a general store.

Six Key Points

5V and 12V Must Not Be Used Interchangeably

Reolink indoor cameras generally use 5V power, while outdoor cameras generally use 12V. Plugging a 12V power adapter into a 5V camera will usually burn out the power board immediately — this type of failure is not covered by the warranty.

Conversely, using a 5V power adapter with a 12V camera will cause the camera to keep restarting or fail to start, and may also result in damage. Be sure to check the label on the camera before placing your order.

• Indoor Cameras 5V, Outdoor Cameras 12V
• Plugging 12V into a 5V Camera May Burn It Out
• Check the Camera Label Before Ordering

5V 2A Current Headroom

5V 2A provides 10W of output headroom, which is sufficient for general indoor dome cameras, including those with infrared LEDs. If your camera supports a pan-tilt motor or auxiliary light, its startup current will be higher, making sufficient headroom even more important.

When a low-quality power adapter is labelled 5V 2A but cannot deliver sufficient actual output, common symptoms include screen flickering or the camera restarting when the infrared LEDs activate.

• 10W Output Headroom
• Pan-Tilt Motors and Auxiliary Lights Have Higher Startup Current
• Low-Quality Power Adapters May Cause Screen Flickering

UK 3-Pin Plug and Indoor Use

The UK 3-pin plug is suitable for Hong Kong sockets. A waterproof box is not required for indoor use, but avoid placing the plug where it may be exposed to splashing water, such as in the kitchen or near a balcony.

If the cable needs to be routed along a wall, we recommend using cable trunking or fixing clips to prevent long-term tension from loosening the connector.

• UK 3-Pin Suitable for Hong Kong Sockets
• Avoid Locations Prone to Water Splashes
• Secure the Cable with Cable Trunking

When to Replace It

The power adapter is a consumable item. If the camera cannot power on (first confirm that the socket has power), restarts when the infrared LEDs activate, or the adapter itself becomes abnormally hot, it should be replaced.

Before replacing it, unplug the power and confirm that the voltage, current, and polarity of the new adapter match the original.

• Replace Immediately if It Becomes Abnormally Hot
• Unplug Before Replacement
• Confirm Matching Voltage, Current, and Polarity

Purchase Recommendations

Indoor units typically come with one power adapter per unit, so a spare is rarely needed. If you are planning to relocate or rewire, or if the original power adapter has been lost, purchasing one with the original specifications is more reliable than buying a universal adapter.

Common Misconceptions About Indoor Unit Power Supply

Misconception 1: Higher current is always better. The current rating of a power adapter is the maximum it can supply; the device only draws the current it needs. Therefore, using a 5V 3A adapter with a 5V 2A device will not cause damage (provided the voltage is the same and the polarity is correct). However, insufficient current can make the device unstable.

Misconception 2: A USB charger can be used as a replacement. Phone chargers usually provide USB-A／USB-C output, with different connectors and polarity. Some chargers also experience greater voltage fluctuations when the load changes, so they may not provide stable power to infrared lights.

Misconception 3: Power adapters can last forever. Capacitor degradation occurs gradually, and many cases of a “broken device” can be resolved by replacing the power adapter. If your indoor unit has been in use for three or four years and experiences random disconnections, it is worth replacing the power adapter first for testing.

• Current is the maximum available, not a forced output
• USB chargers are not recommended as replacements
• After three or four years, replace the power adapter first for testing
