    Сделал заказ, оплатил картой. В течении суток продавец проверил оплату, скомплектовал и отправил заказ. Был присвоен ID номер который отслеживался полностью. Заказ пришёл на двадцать первый день без повреждений. Товар полностью соответствует описанию. Заказывал две платы, они проверены в работе. Всё работает. Продавец надёжный. Советую всем.

    hassle-free but out of stock came a little late due to, whether you use the device / machine / led as a power source to run or use the battery / battery to charge. besides the voltage can do current adjustment, especially the LED is ideal for burning and use as a charger.

    small step down inverter with variable input and output voltages, it can be used in all cases you have a higher voltage and you have to lower it as desired, The maximum current draw must be 1A. In my case I will use it as an adjustable power supply coupled with a diy powerbank.
