The SJCAM C300 is a compact 4K action camera built around a small camera unit that can be paired with a larger battery module carrying a second touchscreen. SJCAM’s official page lists 4K at 30fps, 1080p at up to 120fps, 20MP photos, six-axis gyro stabilisation, dual 1.3-inch touchscreens and up to 6 hours of continuous HD recording with the extended battery setup. It suits vloggers, cyclists and live streamers who care more about long recording sessions than about top-tier image quality.
Short verdict: the C300 is one of the more flexible budget action cameras on paper, thanks to its modular battery and features such as pre-recording, webcam mode and live streaming. Its limits are equally clear: 4K tops out at 30fps, the official page lists a 128GB card limit, and the Amazon.in listing’s “7 hours” claim is higher than SJCAM’s own “up to 6 hours”.
A note on method: this guide is based on SJCAM’s official C300 product page and the Amazon.in listing (both checked on 17 October 2026). It is not based on hands-on testing, and we did not find an independent review with measured results that we could open and cite.
Quick verdict
- Best for: long rides, walking vlogs, classes and live streams where battery life matters more than maximum resolution
- Skip if: you need 4K at 60fps, a waterproof body without a case, or high-end low-light performance
- Key strengths: dual touchscreens, swappable battery design, 1080p at 120fps for slow motion, 60-second pre-recording, webcam and live-stream support, dual-band Wi-Fi
- Key limitations: 4K limited to 30fps, waterproof only in the case, 128GB card ceiling (official), no published sensor size or weight on the official page
How the C300’s modular design works
SJCAM’s official spec table compares two configurations. The C300 Pocket is the camera unit on its own: 68.5 x 32.1 x 25.5 mm, a 1.3-inch touchscreen and a 1000 mAh removable battery, with no secondary screen. The C300 adds a 2800 mAh battery module and a second 1.3-inch touchscreen, growing to 133 x 41 x 25.75 mm. SJCAM says this extended setup provides up to 6 hours of continuous HD recording, and that actual runtime depends on resolution, frame rate, stabilisation, Wi-Fi and screen use.
The Amazon.in listing we are covering is titled “SJCAM C300 4K Pocket Action Camera”, but it also describes a dual-touch-screen body and a dual-battery design with up to 420 minutes (7 hours) of use. That description matches the full C300 configuration with the battery module. Because the word “Pocket” appears in the title, check the listing images and the box contents section to confirm the battery module and second screen are included before you order.
Why this matters in practice: with the module attached you get a front-facing screen for selfie framing and a much bigger battery. With the camera unit alone, you get a smaller, lighter camera for tight spots such as a cap clip or a small helmet mount.

Video and photo: 4K30 with a fast 1080p mode
The C300’s top video mode is 4K at 30fps, according to SJCAM. That is fine for travel clips, talking-head vlogs and landscapes, but fast action looks smoother at higher frame rates. For cycling, skating or children’s sports, the more useful modes are 2K at 60fps and 1080p at 120fps. Shooting 1080p at 120fps lets you slow a moment down to a quarter of its speed in a 30fps edit, which is the classic action-camera trick.
The official page does not state the sensor size or aperture. The Amazon.in listing lists f/2.8 and a CMOS sensor. The listing’s “8X zoom” is not mentioned on SJCAM’s page, which lists a single fixed lens angle, so any zoom is most likely digital: it crops into the image and reduces detail, so treat it as a framing convenience rather than real zoom.
SJCAM lists a 154-degree field of view. That is wide enough for helmet and handlebar shots, though a little narrower than the 170-degree figures some budget rivals advertise. Indoors, it also means you need to hold the camera closer to your face for vlogging.
Stabilisation and audio
SJCAM describes six-axis gyro stabilisation that helps reduce shake during cycling, hiking and running. This is electronic stabilisation, so it works best in daylight and usually crops the frame slightly. For the smoothest results on a motorcycle, mount the camera on a helmet or chest harness rather than the handlebar.
On audio, SJCAM’s page lists a digital microphone, and the Amazon.in listing claims noise reduction that identifies human voices and reduces background noise. Neither source gives measurable details. If speech clarity matters, for example for a course or a walking vlog in traffic, plan to test it early, and consider whether a separate microphone setup fits your workflow.
Battery life: 6 hours or 7?
SJCAM’s official page says the extended battery setup supports up to 6 hours of continuous HD recording. The Amazon.in listing says up to 420 minutes (7 hours) after a full charge. The difference may come from different settings, but neither source publishes the exact test conditions, so plan around the official figure. Recording in 4K, keeping both screens on or using Wi-Fi will reduce runtime further.
The camera charges through USB Type-C with a 5V 2A input, per the official page. That low input means an ordinary phone charger or power bank can top it up, but it also suggests recharging the 2800 mAh module may take a while. SJCAM does not publish a charging time.
Features that make it useful beyond sports
- Pre-recording: SJCAM’s page lists a 60-second pre-recording function, which keeps a rolling buffer so you can save the moment just before you press record
- Webcam mode: the page says the C300 can join video calls as a webcam, useful for online classes or meetings
- Live streaming: listed as supported, which suits creators who stream rides or events
- Car mode: listed on the official page, but remember the official operating range tops out at 45 degrees C, which a parked car’s dashboard in an Indian summer can exceed
- Remote control and app: SJCAM says the C300 connects to the SJCAM app for preview, file management and sharing
- 50Hz or 60Hz setting: set it to 50Hz in India to reduce flicker under tube lights and LED lighting
About “5G Wi-Fi” on the listing: this refers to 5GHz Wi-Fi for faster transfers to your phone, not 5G mobile data. SJCAM’s page confirms dual-band 2.4GHz and 5GHz Wi-Fi.
Waterproofing: use the case
SJCAM states the C300 can be used at depths of up to 30 metres with the waterproof case. Neither source rates the bare camera, so treat the C300 as needing the case for swimming, snorkelling, heavy rain and river crossings. Leak-test the empty case before each water session, and rinse it after salt water. The listing title mentions helmet mount kits, but neither source itemises every accessory, so check whether the waterproof case is in your box.
Who should buy the SJCAM C300
Good fit: riders and cyclists who record long sessions, teachers or creators who want a small camera that doubles as a webcam, and anyone who values a front screen and long battery life over maximum resolution. If you are assembling lights and mics around it, our YouTube starter kit guide for India may help.
Skip it if you want 4K at 60fps or higher for fast action, need a waterproof body without a housing, want 10-bit or log colour (neither source mentions it), or plan to use cards larger than 128GB.
Alternatives worth comparing
- IZI One Lite: according to its Amazon.in listing, it offers 4K at 60fps, a 2-inch rear and 1.3-inch front screen, EIS, two batteries and a 30m case, but we could not find an official spec page and its listing figures conflict in places
- DJI Osmo Pocket 3: DJI lists a 1-inch CMOS sensor, a 3-axis mechanical gimbal, 4K up to 120fps and 10-bit D-Log M. It is a vlogging camera, not an action camera, and its Amazon.in listing marks it as not water resistant
Before you order: a checklist
- Configuration: confirm the listing includes the 2800 mAh battery module with the second screen, since the title also uses the word “Pocket”
- Memory card: the listing title says a 64GB SD card is included, but its technical details show the style as “No Card”, so check the box-contents section and the seller’s description
- Card limit: SJCAM’s page lists microSD up to 128GB, so do not buy a larger card expecting it to work
- Colour: this listing is the Black version
- Warranty and service: the listing data we captured does not state warranty terms; read the warranty section and seller details, and keep the invoice
- First day: format the card in the camera, set 50Hz, update firmware if the app offers it, and test every mode while you are still within the return window
Once you have checked those points, see the SJCAM C300 listing on Amazon.in to confirm the bundle.
Frequently asked questions
Does the SJCAM C300 record 4K at 60fps?
No. SJCAM’s official page lists 4K at 30fps as the maximum 4K mode. Higher frame rates are available at 2K (60fps) and 1080p (up to 120fps).
Is the SJCAM C300 waterproof?
SJCAM says it can be used up to 30 metres underwater with the waterproof case. Neither the official page nor the listing rates the bare camera, so use the case around water.
How long does the C300 battery last?
SJCAM’s official figure is up to 6 hours of continuous HD recording with the extended 2800 mAh battery setup. The Amazon.in listing claims 7 hours. Expect less in 4K or with Wi-Fi and both screens on.
What is the difference between the C300 and the C300 Pocket?
Per SJCAM’s spec table, the C300 Pocket is the camera unit with a 1000 mAh battery and one screen. The C300 adds a 2800 mAh battery module with a second 1.3-inch touchscreen.
Can I use the C300 as a webcam?
Yes, SJCAM’s page lists webcam use for video calls, and live streaming is listed as supported.
Bottom line
The SJCAM C300 makes the most sense for people who record for long stretches and want a front screen, pre-recording and webcam use in one small camera. It is not a high-frame-rate 4K camera and it needs a case for water, so match it to how you actually shoot. If the listing confirms the full battery-module configuration and card you want, check the current price of the SJCAM C300 on Amazon.in.
