As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
I have a new Nano VNA V2 Plus 4. I am just now charging the battery, so I have not had time play with the Vna a lot. But there does not seem to be battery level indicator on the LCD. There are some leds blinking, but they'll be invisible, when I close the box.
Charge LEDS are visible on the flat bottom face of the device.

Hello. I just received my Nano VNA V2 Plus, and I'm surprised: there is no battery? Or is it not connected?
It only works when plugged into a USB port. I hesitate to open it so as not to lose the guarantee.
Thank you for your reply.

It is shipped without a battery. It takes an 18615 without tabs and without protection circuit that fits into an internal battery holder. The claim is shipping with li-ion battery is problematic.
