Pros & Cons
Pros
- ✓ Seven selectable outputs (3V-12V) replace multiple dead adapter bricks from one unit
- ✓ Eight tips included: 5.5x2.5, 4.8x1.7, 4.0x1.7, 3.5x1.35, 3.0x1.1, 2.5x0.7mm, Micro USB, LED
- ✓ Over-current, over-voltage, and short-circuit protection built in
- ✓ 100-240V 50-60Hz input works on foreign mains without a separate travel transformer
Cons
- ✗ 1.25A / 15W ceiling rules out 3.5-inch drives, larger LED strips, and most powered hubs
- ✗ Center-positive polarity only, so center-negative gear (many pedals) needs a different supply
- ✗ Wrong voltage selection can damage the connected device, no auto-detection
- ✗ Bare LED terminal connector requires wiring, not a plug-and-play tip for beginners
Manufacturer description
The Outtag 15W universal power supply solves the drawer-full-of-mismatched-bricks problem with one adapter that covers seven DC voltages. A sliding selector steps output between 3V, 4.5V, 5V, 6V, 7.5V, 9V, and 12V at up to 1.25A, so a single unit can replace a dead 5V 1A router brick, a 9V 1A effects-pedal supply, or a 12V CCTV camera adapter. Input is universal AC 100-240V 50-60Hz, which means it travels without a separate transformer. Eight interchangeable tips ship in the box: 5.5x2.5mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, a Micro USB plug, and a bare LED terminal…
SpecPicks Verdict
SpecPicks scored Outtag 3V 4.5V 5V 6V 7.5V 9V 12V 1250mA 15W Power Supply 5.5 * 2.1mm using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Outtag's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
What voltages does this adapter actually output?
Seven fixed steps: 3V, 4.5V, 5V, 6V, 7.5V, 9V, and 12V DC, at up to 1.25A (15W total). Input is AC 100-240V 50-60Hz.
Will it power my external hard drive?
It handles 2.5-inch bus-style external drives within the 1.25A limit. A 3.5-inch desktop drive typically needs 12V at 1.5A or more, which exceeds this 15W supply.
What size plug and tips are included?
The cable ends in a 5.5x2.1mm barrel plug, plus 8 tips: 5.5x2.5mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, Micro USB, and an LED terminal connector.
Is it center-positive or center-negative?
Inner positive (+), outer negative (-). Check your device's polarity marking first, since center-negative equipment needs a different adapter or a polarity-reversing tip.
