Questions and answers

Is the SJCAM C300 worth it?
At $107.99 at eBay as of November 4, 2026, it is a cheap way to get 4K, stabilization and WiFi. It suits casual filming; serious action shooters should expect better stabilization and low-light results from pricier cameras.
Does it need a waterproof case?
The camera is listed as waterproof, so it can handle wet use without an add-on housing. Check the depth rating before diving, since budget action cameras often have modest limits.
How long does the battery last?
The rated battery life is up to 7 hours, which likely assumes lower resolution and settings. Expect much less at 4K with stabilization and WiFi on.
What comes in the box?
The listing is marked as a bundle, but the exact contents are not spelled out. Confirm whether a microSD card and mounts are included before ordering, since storage is required and not guaranteed.
Does it work with a phone?
Yes. It has 2.4G/5G WiFi and streams to the SJCAM app for preview and transfer. Dual-band WiFi gives a more stable connection than 2.4G alone.
When is it cheapest?
The current best new price is $107.99 at eBay as of November 4, 2026, across 5 stores. Budget action cameras usually drop around Black Friday and Prime Day, so watch the price history then.
