Questions about this product
- Will this power adapter work with my security cameras and LED strip lights?
- Yes, if your devices need a 12V DC input and use a standard 2.1mm by 5.5mm barrel jack. It handles international AC inputs from 110V to 220V automatically. Just make sure your total power draw does not exceed 4 amps.
- Can I use this 4A adapter if my device only requires 2 amps?
- Absolutely. Your device only draws the current it needs, so this adapter works fine for smaller 1A or 2A loads. However, do not use this with devices requiring more than 4 amps or 48 watts. Doing so can overload the adapter and cause damage.
- What is the outer case made of, and does it get very hot?
- This adapter features a metal housing that dissipates heat much better than typical plastic cases. It uses passive convection cooling, meaning there is no noisy internal fan. It runs cooler and lasts longer during continuous 24/7 operations.
