What resolution does the X7 record?

It records video up to 1920x1080, or Full HD. Stills are captured at lower resolution than a phone camera.

Does it need a memory card?

Yes. Video is stored on a microSD card, which is not included, so you need to add one before recording.

It charges over USB-C with a lithium battery built in. Any standard USB-C cable and charger will do.

No. The small sensor and lens need decent light. Indoor evening footage looks grainy and soft.

Not for quality. It is smaller and easier to clip on, but a phone shoots far better video, especially in low light.

Kids, gift buyers and anyone who wants a tiny clip-on recorder for short, casual clips.
