Adjustable AC/DC Power Adapter with 14 Connector Tips
Match a supported device's power requirements with the ALITOVE adjustable AC/DC power adapter. This 3–12V 30W model lists seven selectable DC voltages, a maximum 2.5A output, 14 connector tips and a separate 5V 2.1A USB port reference.
Picture organizing your electronics shelf and checking a device's input label before selecting the matching voltage and connector. This multi-tip adapter offers options for compatible equipment, but the universal wording in the original title does not mean it fits or powers every device.
Features and Benefits
- 🔌 Seven voltage selections: Listed DC outputs are 3V, 4.5V, 5V, 6V, 7.5V, 9V and 12V.
- 🧩 14 connector tips: A selection of barrel, Micro-USB, Type-C and terminal connectors is listed for matching supported equipment.
- ⚡ 30W and 2.5A maximum references: Confirm available output at the chosen voltage; maximum values do not mean 30W is available at every setting.
- 🔋 USB port reference: The original title lists a 5V 2.1A USB port without a verified simultaneous-load allocation.
- ➕ Polarity information: Default polarity is listed as center positive, with a 5.5 × 2.1mm reverse-polarity converter also named.
- 📏 Listed 4.9ft cable: A cable-length reference helps plan placement near compatible equipment.

Compatibility check: Before connecting, match the device's required DC voltage, polarity and connector dimensions, and confirm that its current and power demand are within the adapter's limits. Disconnect power before changing settings or tips. A physically fitting connector alone does not establish electrical compatibility. Do not assume Type-C implies USB Power Delivery or that this is a standalone battery charger.
Frequently Asked Questions
Q: Who is this adjustable power adapter for?
A: It is for shoppers powering electronics whose specified voltage, polarity, connector and load match the exact adapter configuration. Universal wording does not establish compatibility with all household devices.
Q: Can it power my existing electronic device?
A: Compare the device's input requirements with the seven output settings, connector sizes and verified output limits. Do not use it for an AC-input device or equipment outside its supported DC specifications. Maximum 30W and 2.5A ratings are limits, not a guarantee at every combination.
Q: Is it a useful electronics gift?
A: It may suit someone who needs a compatible replacement supply, but it is best chosen against an actual device's requirements rather than by appearance. Gift packaging is not listed.
Q: How do I choose voltage and polarity?
A: Disconnect the adapter, read the device's required DC voltage and polarity, then follow the adapter manual to select the correct configuration. Default polarity is listed as center positive. Use the reverse converter only when appropriate and verify the final output before connecting.
Q: Which tips and USB features are included?
A: Fourteen tips and a 5.5 × 2.1mm reverse-polarity converter are named. The title lists a 5V 2.1A USB port. Simultaneous output limits and fast-charge support are unspecified; the Type-C tip alone does not establish negotiated USB-C charging protocols.
Q: Is this a STEM kit or laboratory power supply?
A: No STEM lessons, experiments or educational accessories are listed. It is an adjustable device power adapter, not an established precision laboratory supply or battery-charging kit. Use only for compatible applications described in its instructions.
