Universal 5V adapter for low-power devices
This BASEUS unit converts AC 100-240V mains power to a regulated DC 5V output at up to 4A, delivering 20W maximum. The 4.9FT cable and eight interchangeable tips let it replace lost or damaged chargers for development boards, security cameras, baby monitors, LED strips and similar 5V electronics. Centre-positive polarity matches the majority of consumer barrels and micro connectors.
Output current ceiling of 4A at 5V
The adapter will safely supply any device that draws 4A or less at 5V, automatically providing the exact amperage the load requires down to 100mA. Equipment needing more than 4A or a different voltage cannot use this supply, so buyers with higher-current single-board computers, motor-driven projects or 12V gear must look elsewhere.
Eight tips cover common barrel and USB sizes
Included plugs are 5.5×2.1mm (also fits 5.5×2.5mm), 4.0×1.7mm, 3.5×1.35mm, 3.0×1.1mm, 2.5×0.7mm, Micro-USB and Type-C terminals. This assortment eliminates the need to source separate cables for Raspberry Pi, Jetson Nano, Odroid, CCTV cameras, routers, Kindle Fire tablets and WS2812B/WS2811 LED projects.

Questions about this item
How much power does the 20W rating actually deliver to a device like a Raspberry Pi?
The adapter supplies up to 4A at 5V, so a Raspberry Pi or similar board draws only the current it needs up to that 4A limit.
What does the 100-240V input range mean for everyday use?
The unit accepts any mains voltage from 100V to 240V at 50 or 60Hz, so it works on standard household outlets worldwide without a separate voltage selector.
Which of the eight included tips will fit a 5.5 x 2.1 mm barrel jack?
The set includes a 5.5 x 2.1 mm plug that is also compatible with 5.5 x 2.5 mm sockets, plus seven other sizes ranging from 2.5 x 0.7 mm up to 4.0 x 1.7 mm, plus Micro-USB and Type-C connectors.
