SHNITPWR 5V 5A DC Power Supply Adapter 5 Volt 5 Amp 25W AC 100V~240V to DC Converter Transformer LED Driver with 5.5x2.5mm DC Tip for WS2812B WS2813 LED Pixel Strip TV Box USB HUB Raspberry Pi Arduino

Input: AC 100 - 240V, 50 / 60Hz ; Output: DC 5V, Max 5A/5000mA, 25W ; It means that it can supply with all amperage less than 5A. ---such as 500mA, 1A, 2.5A, 3A,4A,5A, all are available. For example, if your device draws 3A then 3A will be supplied. If draws more than 5A, only 5A will be supplied and power supply will be damaged soon. NEVER OVERLOAD! Output DC adaptor jack size is 5.5mm x 2.5mm. In order to meet more requirements,we give away a female DC connector. You can screw wires onto it easily, no soldering required. Certified by FCC CE ROHS. We focus on producing high quality power adapters. No noise, low temperature operation, no spontaneous combustion, no explosion, no fire hazard, stable output. Automatic overload cut-off, over voltage cut-off, automatic thermal cut-off, short circuit protection.

Check Voltage 1. Please find the spec label of your device and check the working voltage. It should be 5V DC, not be AC 5V or lower/higher than 5V DC. Otherwise, your device will not work or be damaged. 2. Check Current 2. Check the max current your device will draw. It should be equal to or less than 5A,such as 1A,2A,3A,5A. Otherwise, your device won’t work well and the power supply will be damaged very soon. 3. Check Power Port 3. Check the power input port of your device. Its outer diameter should be 5.5mm; inner core diameter should be 2.5mm or 2.1mm. Inner core polarity should be"+", exterior polarity should be" - ". 4. Check Original PS 4. If you have a power supply for reference, their output voltage, plug size, polarity should be the same .If our PS’s current is equal to or higher than original one’s, then our PS will work with your device.
