Description
Universal Power Supply, Variable DC Power Supply 3-24V with LED Display and 15 Tips
-
A universal power supply for most of what you own: turn the knob to 3-24V and swap the tip for LED strips, routers, speakers and more
-
One universal AC adapter, not a drawer of chargers: it steps down to a clean DC output for most small household electronics
-
Finally fits the device you actually own: 15 interchangeable tips, including the original 0.2x0.1 in size, cover most small electronics
-
Dial in the exact voltage, see it confirmed: the rotatable knob sets 3 to 24V and the LED display shows the live reading before you plug in
-
Cut the power without unplugging: an independent power switch shuts it off right at the adapter
You've hunted through a drawer of mismatched chargers before, digging for the one that actually fits — this power supply is built to end that search. Turn the knob to the voltage your device calls for, from 3 to 24 volts DC, and choose from 15 tips (including the original 0.2x0.1 in (5.5x2.5mm) size) until one clicks into place; the LED display confirms the setting before you plug in, so you're never guessing at the voltage.
Inside, it steps AC 100-240V mains down to a clean, adjustable DC output of up to 5A across steps from 300mA to 5A, making it a capable ac dc power adapter for LED strips, under-cabinet lights, TV boxes, smart speakers, Wi-Fi routers, essential oil diffusers, USB fans, Wi-Fi cameras, USB hubs and hard disk enclosures. An independent power switch lets you cut power at the wall without unplugging, and matching the correct voltage to your device — and keeping the load under about 80% of the rated maximum — helps it run reliably.
