Its maximum 2A (2000mA) output and 5-foot power cord ensure a comfortable distance for everyday use. Built-in overvoltage, overcurrent, short-circuit, and overtemperature protection prevents malfunction or damage due to voltage anomalies, ensuring stable operation
- 8 CHANGEABLE ADAPTER PLUGS: optional adapter tips: 5.5*2.1 mm, 4.8*1.7 mm, 4.0*1.7 mm, 3.5*1.35 mm, 3.0*1.1 mm, 2.5*0.7 mm, Micro-USB, LED terminal connector; Versatility and space saving convenience of having one base and all shapes of charge plugs in one place, you are able to choose different adapter tips and use them for various household electronics (Please measure the adapter size before order to avoid incompatible issue)
- MULTI PURPOSE COMPATIBILITY: With 7 adjustable voltages + 8 replaceable plugs, this adapter is compatible with 99% of 3V-12V household electronics (e.g., Tablet PC, LED Strip Lights, Keyboard, Scales, Routers, Speakers, CCTV Camera System, USB Charging Camera, DVD/CD Player, USB Hub, Recorder, Exercise Bike, Clock, Trail Camera, Weather Station) (Note: Not Compatible USB-C/ Radio/Laptop/ Over 12V DC device! )
- SUPPORT 1A 1.5A 2A OUTPUT: This universal power supply supplies 2 Amps max output current at 12 Volt (Max) to 3 Volt( Min), and backwards compatible with less than 2A, such as 1.8A 1.6A 1.5A 1.3A 1.2A 1A 0.9A 0.8A 0.75A 0.6A 0.5A 0.3A 0.1A 2000/1500/1000/500mA; (Key Tip: If "Not Working" occurs, first check two points: 1. Is the voltage position locked (use the included voltage key to lock; failure to do so will result in unstable power supply); 2. Is the polarity of the device consistent with the adapter (center positive +; reverse polarity will result in a non-functional connection)
- UNIVERSAL ADAPTER: SoulBay ac/dc adaptor is easy to select the output voltage and convert to different volt with ease using the provided key, simple plug and use, one charger replaces many; NOTE: DC Plug Polarity: inner Positive(+), outer Negative(-), Polarity is Not reversible ((if the device current exceeds 2A, the protection mechanism will trigger a "failure"; this is not a product malfunction)
- Troubleshooting: 1. Is the voltage position locked (Voltage must match the DC Output of your device); 2. Is the polarity of the device consistent with the adapter (Center positive +; reverse polarity will result in a non-functional connection); 3. If the polarity and voltage are correct, Check if the required output current are more than 2A
