Key Details
| Detail | Verified information and buyer relevance |
|---|---|
| Product type | AC to DC power adapter – a wall charger for compatible low-power devices. |
| Input | AC 100V to 240V, 0.25A, 50/60Hz, so it is set up for mains-powered use within that input range. |
| Output | 3V, 4.5V, 5V, 6V, 7.5V, 9V or 12V. |
| Maximum output | 1000 mA maximum, so the connected device must stay within that limit. |
| Connector set | 8 connection tips are included, plus a Micro USB-B plug. |
| Tip sizes | 2.5 x 0.7 mm, 3.0 x 1.1 mm, 3.5 x 1.35 mm, 4.0 x 1.7 mm, 5.5 x 2.1 mm, 5.5 x 2.5 mm, LED terminal connector and Micro USB-B. |
| Protection | Over-voltage, over-current, short-circuit and over-temperature protection are stated. |
| Limitation | Not compatible with laptops or other high-power equipment, and polarity cannot be reversed. |
What to Compare Before Buying
- Voltage: Match the device’s required voltage to one of the available outputs: 3V, 4.5V, 5V, 6V, 7.5V, 9V or 12V.
- Current demand: Check that the device draws no more than 1000 mA.
- Connector fit: Compare the device socket with the supplied tips, including the Micro USB-B plug and the listed barrel sizes.
- Polarity: This adapter does not allow polarity reversal, so the plug arrangement must suit the device.
- Power level: It is not for laptops or other high-power equipment.
When to Consider a Different Option
Choose a different adapter if your device needs more than 1000 mA, requires a different plug type, or depends on reversed polarity. It is also not the right choice for laptops or other higher-power equipment.
Before You Decide
Confirm the required voltage, current draw and connector type for your device before choosing an offer. If your device needs reversed polarity or higher power, this adapter will not be the right fit.
Common Buyer Questions
Does it work with several voltages?
Yes, the adapter offers selectable output at 3V, 4.5V, 5V, 6V, 7.5V, 9V and 12V.
Are the connector tips included?
Yes, 8 connection tips are included, along with a Micro USB-B plug.
Is it suitable for laptops?
No, it is stated as not compatible with laptops or other high-power equipment.
Can the polarity be reversed?
No, polarity could not be reversed.
Using It in Practice
For low-power devices such as routers, speakers or LED strip lights, the main checks are the required voltage, the connector size and the device’s current draw. Matching those three points is more important than the number of included tips.
Safe Use and Important Precautions
Follow the device’s own power requirements and the manufacturer’s instructions before use. Do not use this adapter with laptops or other high-power equipment, and do not rely on it if reversed polarity is required.
Before You Decide
Confirm the required voltage, current draw and connector type for your device before choosing an offer. If your device needs reversed polarity or higher power, this adapter will not be the right fit.
