Mini DIGITAL PWR / SWR meter Review by Pal Om0et (in English):
The power supply is a built-in 3.7V 1000mAh battery, which can be recharged through a conventional USB-C-connector mobile phone charger (5V/1A). The CQV-Swr120 has the possibility to save the battery, that is, the meter can be turned off when it is inaction and on when it detects VF power. Of course there is a battery protection function.
The dimensions are 88 x 63 x 38mm. It is therefore a small device that complements the antenna tuner, amplifier or transceiver without a built -in meter. The current price is around 50 €.
