The Addtam Surge Protector Power Board offers a versatile solution for users needing to power multiple devices at once. It comes with 8 widely spaced power outlets and 4 USB ports (including 2 USB-C), allowing up to 12 devices to be connected simultaneously, which is great for home or office setups where space and multiple gadgets are common. The 1.8-meter extension cord with a 10A current capacity ensures it can handle typical household loads safely.

A standout feature is its 900-joule surge protection rating, which provides basic defense against power spikes and electrical surges to protect your valuable devices like TVs, computers, and printers. The built-in double switches allow you to control power on each side independently, adding convenience and safety. An indicator light confirms when surge protection is active, giving you peace of mind. The powerboard is made with fire-resistant materials to reduce fire risks. However, it does not specify an IP rating, so it’s not designed for outdoor wet environments or harsh weather conditions, making it more suited for indoor use.

The included mounting design is a plus, letting you fix it neatly on walls or desks. This power board is a reliable choice for indoor use where multiple electronic devices need organized and protected power access, but it should not be used in outdoor or rugged conditions where water resistance is important.

Addtam Surge Protector Power Board - 6 Widely Outlets with 4 USB Ports(2 USB C Outlets), Power Strip with 1.8M Extension Cord, 900J Surge Protection, Flat Plug, Wall Mount for Home OfficeAddtam
amazon-logoView Product

The Addtam Surge Protector Power Board offers a versatile power solution with 6 standard outlets and 4 USB ports (including 2 USB-C), allowing you to charge up to 12 devices at once. Its 900-joule surge protection rating provides a basic level of defense against power spikes, which is suitable for protecting common household or office electronics. The 1.8-meter extension cord is a decent length for flexible placement, and the flat plug design helps save space near walls.

Safety is emphasized through overload, overcurrent, and short circuit protection, and the power strip is made from flame-retardant materials for added reliability. It also features screw holes on both ends for easy wall or desk mounting, making it convenient to keep your charging station organized. However, this model lacks a weatherproof or waterproof rating, which means it is not designed for outdoor use or environments exposed to moisture. The maximum wattage of 2400 watts and 10 amp current capacity should be sufficient for typical indoor devices but may not support heavy-duty outdoor equipment.

If you’re looking for a surge protector primarily for indoor home or office use with multiple USB charging options and mounting capability, this power board presents a solid choice. For those needing outdoor suitability or higher surge protection ratings, other products designed for those specific conditions may be more appropriate.

The Addtam Power Board offers a versatile charging solution with 6 AC outlets and 4 USB ports (including 2 USB-C), making it great for powering multiple devices at once in home or office settings. Its 900 joules surge protection helps guard electronics like computers and TVs against power spikes, though this rating is moderate compared to heavy-duty outdoor surge protectors.

The 1.8-meter cord and wall-mountable design add convenience, allowing flexible placement and easy installation. It also features an on/off switch and built-in safety against overloads, over-current, and short circuits, which enhances device protection. However, this power board lacks an IP or weatherproof rating, meaning it’s not designed to withstand outdoor elements such as rain or dust.

For indoor or sheltered environments needing multiple outlets and fast USB-C charging, it is a solid, reliable option with smart charging technology that adjusts power for efficient device charging.

Buying Guide for the Best Outdoor Power Surge Protectors

Choosing the right outdoor power surge protector is essential because it shields your valuable outdoor electronics—such as garden lights, security cameras, and decorative features—from sudden spikes in electricity that can damage or even destroy them. Since outdoor environments pose additional risks with rain, dust, and temperature extremes, making a careful and informed choice ensures not only protection from power surges but also long-lasting performance and safety for everyone using the equipment.
Surge Protection Rating (Joules)The surge protection rating, measured in joules, tells you how much energy the surge protector can absorb before it stops protecting your devices. Higher joule ratings indicate better protection against bigger or more frequent surges. For light outdoor use like string lights, a lower joule rating may be sufficient, but for sensitive or expensive equipment like pumps or security cameras, a higher rating gives more robust protection. Assess what devices you’re plugging in, and if you anticipate frequent storms or unstable power, lean towards higher joule values for extra safety.
Weatherproof/Waterproof Rating (IP Rating)Outdoor surge protectors need to withstand rain, dust, and other weather elements. The IP (Ingress Protection) rating refers to how well the device stays protected against solids and liquids; for example, IP44 or IP65. A higher IP number means better resistance. If your protector will be exposed directly to rain or sitting on the ground, choose a higher IP rating to avoid water damage. If used under cover or in a protected space, a moderate rating may suffice.
Number and Type of OutletsThis spec tells you how many devices you can plug in at once and whether the outlets fit different plug types or include spaces for bulky adapters. More outlets are useful for setups with multiple devices, but if only powering one item, a single-outlet protector keeps things simple. Consider the types and sizes of plugs you use, and make sure the arrangement accommodates all your equipment without crowding.
Cord LengthCord length determines how far the surge protector can be from your main power source. Longer cords offer flexibility in placing your devices where you want them, but can become a tripping hazard or get tangled. If your outlets are close to your devices, a shorter cord keeps things tidier, while a longer cord is best for reaching distant locations in your yard or patio.
Maximum Amperage/Current CapacityThis number, measured in amps, shows the maximum current the surge protector can handle safely. If you plan to connect high-power items—like pool pumps or lawn equipment—make sure the protector has sufficient amperage. Light-use cases, such as garden lights or small appliances, can use units with lower ratings. Always compare your devices’ amp requirements to the surge protector’s ability for safe operation.
Indicator Lights or Diagnostic FeaturesMany outdoor surge protectors come with indicator lights or simple displays that show if your surge protection is active or if there’s a fault. These features make it easy to check at a glance whether your devices are protected. If you prefer peace of mind and regular status checks, choose a model with clear and weather-resistant indicators.
Mounting OptionsThe way your surge protector mounts—such as ground stakes, wall mounts, or hanging hooks—affects how securely you can place it outdoors. If you need to move it around, a portable design with a stake may be preferable. For permanent installations or to keep it off wet surfaces, look for wall or post-mounted options. Match the mounting style to your intended use and the environment it will be placed in.
