Frequently Asked Questions

Q: What devices can this power supply be used for?
A: This adapter is compatible with a wide range of low-voltage DC devices including LED strips, routers, CCTV cameras, radios, small appliances, Arduino/Raspberry Pi projects, and any device requiring 3V–12V DC power up to 2.5A.

Q: How do I know which voltage to select?
A: Check the label on your device for its required input voltage (e.g., "DC 9V 1A"). Set the adapter to that voltage using the selector switch. Never exceed the device's rated voltage.

Q: What does the reverse polarity converter do?
A: Some older devices use a reversed polarity (negative inside, positive outside). The included 4cm reverse polarity converter for the 5.5x2.1mm tip allows you to power these devices safely. Always check your device's polarity before use.

Q: Can I use this internationally while travelling?
A: Yes! The universal 100V–240V input works with power outlets in Canada, the US, Europe, Asia, and most countries worldwide. You may need a plug adapter for different socket types.

Q: Is it safe to use at full 30W continuously?
A: ALITOVE recommends using no more than 80% of the maximum load (i.e., under 24W) for extended use to preserve the power supply's lifespan and maintain safe operating temperatures.

Q: Does it include a Type-C tip?
A: Yes! The 14-tip set includes a Type-C connector, Micro-USB, a DC terminal connector, and 11 barrel connector sizes to cover virtually all common DC-powered devices.
