A:AnswerI personally have not upgraded my ACER Helios 300 RAM as of now since it has not been slow on most application I use, but I would say yes you should get 2 - 16gb 4800 mhz ddr5 or 1- 32gb 4800 mhz ddr5 to upgrade the RAM in the computer.
A:AnswerNo.. doesn't look like it. It has a bigger battery instead. It does have two SSD nvme m.2 slots internal, so you can add a second drive there at least. Heat could potentially be an issue.
A:AnswerHere are the specs for the TB4 port:
Connects to USB devices with a TBT4 Type-C connector.
• Supports HDMI 2.1/DP1.4
• Supports Thunderbolt4
• Delivers up to 3A at 5V up to max 15W DC for USB charging
• Not support power delivery
A:AnswerAll Acer laptops ship with an AC adapter that supports 100v-240v. The only thing you would need is an adapter for the plug end of the US power cord to fit the outlets outside North America.
A:AnswerYes it does. Under best buy specs connections it indicates HDMI 2.1 output. I uploaded a screenshot of the setup guide that indicates the same. Hope that helps.
