Description
【Say goodbye to the trouble of cable length】Are you still bothered by the fact that the power cord is not long enough? This 12V 3.5A power adapter is equipped with a 6.5-foot-long high-quality pure copper core power cord, allowing you to use it anywhere you need.
【New Upgrade】We have added a switch device to the 12-volt DC power cord, allowing you to power off the device with one click without unplugging the power supply, which is very convenient and fast. It can also reduce the number of plugging and unplugging operations, avoiding the loosening of the power jack caused by multiple plugging and unplugging.
【Basic Parameters】Input: 100-240V 50/60Hz, Output: 12V 3.5A, Maximum power: 42W, Power plug size: 5.5mm × 2.5mm (compatible with 2.1mm), Polarity: Center positive. Please confirm the specification parameters on your device's nameplate before purchasing to avoid buying an inappropriate power supply.
【Safety Performance】This 12V 3.5A voltage converter has built-in overload cut-off, overvoltage protection, overcurrent protection, and short-circuit protection. All units undergo rigorous aging tests before leaving the factory to provide safe and stable power for your equipment.
【Widely Used】This 12V 3.5A conversion power supply is very suitable for small DC-powered electronic devices under 12V 42W, such as routers, LED light strips, ADSL modems, GPS, closed-circuit television surveillance cameras, Bluetooth speakers, network cameras, etc. It should be noted that: it is not waterproof, please do not use it outdoors!

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Gilivier products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
