▼How many hours of continuous movies can you watch on the GV50 in battery mode?
To check the remaining battery level of the GV50, first press the settings button on the remote control while any screen is being projected.
Select 'Battery'.
The remaining battery power is displayed by a battery icon.
According to
The battery icon only tells you the remaining battery level, between 80% and 100%, but while charging, the power button will change from red, which indicates 'charging,' to green, which indicates 'charging is complete.'
After a while, the message 'Battery is too low' was displayed and the GV50 automatically turned off. The time at this time was 12:20, 1 hour and 26 minutes after the start of the movie. The volume during the movie was about '50' on a scale of 1 to 100, and the screen brightness was at its maximum, so the settings were such that a movie could be enjoyed in a fairly large room. If you want to run it for a longer period of time, you will probably need to adjust the volume and brightness.
▼How long does it take to fully charge the GV50 from zero?
If the battery is completely empty, when you press the power button it will flash red and will not turn on.
Insert the charging cable into the power terminal to charge.
When I pressed the power button while connected to the charging cable, the GV50 started up.
When I checked the battery again, the battery level was a red icon indicating '0% to 20%'. From here, I measured the time until charging was complete. Charging started at 13:00. While charging, I turned on the GV50 to check the battery level, but I was not playing any video or music.
After about an hour, the battery will be charged to about 40% to 59%.
It takes about 2 hours to charge from 60% to 79%.
It took about 2 hours and 16 minutes from the start of charging for the battery icon to reach the maximum of 80% to 100%.
The power button turned green at 4:56 p.m. The battery took 3 hours and 56 minutes to fully charge from zero.
▼The GV50 can also be used as a mobile battery
The side of the GV50 is a speaker, and on one side there is an earphone jack, USB-A, HDMI, USB-C, and power terminal. The USB-A port specifications are '2.0/Power Supply1.0A/Reader/FW Upgrade', and the USB-C is DisplayPort/PD input from 20V-2.25A, 5A/PD output is 5V-2A, 9V-2A, 12V-1.5A, 15V-1.2A.
The GV20 can also be used as a portable battery by connecting it to a device with a USB cable. When I connected
▼Summary
The GV50 is compact, with a height of about 21 cm and a width of about 8.5 cm when standing, making it easy to place on a tabletop, and weighs 2.1 kg, making it easy to move and carry around, so the battery mode, which allows you to move it around a bit and use it cordlessly or outdoors, is quite convenient. However, even if you connect it to Google Home, you cannot see details such as the remaining battery percentage or how many minutes it will run, so if you are outdoors and cannot charge it immediately, it is best to use it for about an hour, or use it as a portable battery while only using it for audio, which consumes less battery.
The GV50 is also available on Amazon.co.jp, and the selling price at the time of writing was 119,800 yen including tax.
