The voltage adjustment of this product is supposed to be 3V to 8V, but when I measured it, the range was 2.36V to 7.02V. I own other similar products, and they output up to 8.3V. I don't output up to 8V, so it's OK, but I want you to make sure the performance inspection.
I received the item today, just over two months after I ordered it. Anyway, I'm glad I received the product, but I'm dissatisfied with the delivery period.
