for Samsung SoundBar Power Cord 24V 2.5A Power Supply
Quick take
This 24V DC, 2.5A (60W max) adapter is built to replace the power supply for select Samsung soundbars and wireless audio models that use a compatible barrel-style connector. It also supports other 24V devices that do not exceed 2.5A draw. The main catch is compatibility: the soundbar must match the correct voltage, amperage range, and plug type.
Pros and cons
Pros
- 24V DC output with up to 2.5A (60W max), suitable for 24V devices that draw 0 to 2.5A
- AC input supports 100V to 240V (50 to 60Hz), making it flexible for standard US power use
- Includes a power cord plus add-on barrel connectors for other compatible hardware
- Built with over-voltage, over-current, short-circuit, and over-charge protection claims
Cons
- Not for soundbars that require different specs (for example, listed exclusions include 19.5V and 19V models)
- Connector fit is model-specific, including whether you need a straight connector or a 90-degree style
- Buyer-review evidence is limited, so real-world “works for every listed model” confidence is not absolute
What buyers think
Buyer-review evidence is present but not deep, with most comments staying high level. The recurring themes are that the adapter can work as a straightforward replacement when the barrel plug and voltage expectations match, and that the cord length and overall build feel adequate for day-to-day use. There is also at least one reported case of non-fit for a soundbar, which highlights the importance of checking the exact model requirements and connector shape before ordering.
Key specs and what they mean
This is a 24V DC power adapter with an output of 2.5A (rated 60W max). It’s intended for devices that expect 24V and fall within the 0 to 2.5A power draw range.
- Input: AC 100V to 240V, 50 to 60Hz
- Output: DC 24V, up to 2.5A (60W max)
- Barrel plug size: 5.5mm (outer) x 2.5mm (inner)
- Included: 1x 24V DC adapter, AC cable, and a 2-prong US power cord version
- Add-on ports included: 6.3mm x 2.1mm, and 6.5mm x 4.4mm (useful if your device accepts one of those compatible sizes)
Compatibility checklist before you buy
Power adapters are simple in concept, but the wrong voltage or plug shape can mean “no power” even if the adapter seems close. Before ordering, verify:
- Voltage: your soundbar must match the expected 24V DC input requirement. This adapter is positioned as a 24V replacement.
- Current rating: the device should not require more than 2.5A to operate. The adapter can supply up to 2.5A, but it is not meant for higher-current requirements.
- Connector size: confirm 5.5mm x 2.5mm, or one of the included add-on barrel sizes if applicable.
- Connector angle: check whether you need a straight barrel connector. If your current setup uses a 90-degree connection, you may need a different style.
- Model exclusions: this adapter is explicitly not intended for certain soundbars with different voltage needs, including listed 19.5V and 19V Samsung models.
Who this adapter is best for
This power supply is a strong fit if you:
- Need a replacement charger for a compatible Samsung soundbar or wireless audio system that runs on 24V DC
- Prefer a single adapter that can cover both your soundbar power and other small 24V 0 to 2.5A electronics (for example, certain LED driver or 24V device accessories)
- Want an option that supports common US household AC input and includes the needed power cord
Who should avoid it
Consider skipping this adapter if:
- Your soundbar requires a different voltage than 24V (the product is positioned with specific exclusions for certain Samsung models)
- Your device needs a connector style that is not straight, and you do not want to risk a partial or incorrect fit
- Your hardware requires more than 2.5A continuous draw
Pros and cons in plain language
Pros
- Clear power target: 24V DC, up to 2.5A, which aligns with many 24V accessories and compatible soundbar models.
- Flexible for everyday use: AC input accepts a wide range (100V to 240V), and the adapter includes the necessary AC cable.
- Connector options: includes add-on barrel sizes that can help with cross-device compatibility where the plug size matches.
Cons
- Compatibility is strict: not all Samsung soundbars accept 24V or the same connector, and at least one review indicates a mismatch for a particular soundbar model.
- Limited buyer-detail: review evidence is not extensive, so it’s smart to rely primarily on voltage, amperage, and connector fit rather than sentiment.
Is it worth it?
If you have a Samsung soundbar (or another 24V device) that matches 24V DC and your device’s input expects a compatible 5.5mm x 2.5mm barrel plug, this adapter can be a practical replacement. It becomes poor value if your model requires a different voltage (for example, the listed 19.5V or 19V cases) or if your soundbar input port uses a different physical connector angle.
Alternatives to consider
If you are unsure about compatibility, the safest alternative is to compare using these criteria:
- Exact voltage and current: prioritize adapters that specify the correct output voltage and support at least the device’s needed current.
- Correct plug size and angle: match both barrel dimensions and whether your connection needs a straight or 90-degree connector.
- Model-specific replacements: if your soundbar model is older or uncommon, a soundbar-specific replacement listing often reduces plug-fit risk.
FAQ
What voltage is this power supply?
It outputs 24V DC.
What is the maximum current and wattage?
It outputs up to 2.5A (rated up to 60W max).
What barrel plug size does it use?
The main barrel plug size is 5.5mm x 2.5mm.
Does it come with any extra connector options?
Yes, it includes add-on barrel connector ports sized 6.3mm x 2.1mm and 6.5mm x 4.4mm.
Will this work with every Samsung soundbar?
No. Some Samsung soundbars require different voltage specs or use different charger requirements, so you should confirm your soundbar’s input rating and plug type first.
Is the connector straight?
This is described as a straight connector, so if your soundbar uses a 90-degree connection, you may need a different style.
