Overall G1W and SJ4000 main specifications, performance and video quality recording is the same apart from G1W is uses built-in battery and G1W-C is based on Capacitor ( dual SuperCap ) which allows to save last recorded video clip and keeps time and device settings in the memory.

Till now there are only some Korean high-end dash camera manufacturers used capacitors instead of batteries, but end of 2013y showed more and more high-end dash cam manufacturers realizing problems if using batteries inside dash cams, so they now going over to capacitor based dash cams. But we all know that Korean high-end dash cams are quite expensive and not all people can afford them.

G1W-C is the FIRST Chinese dash camera which is based on Capacitor. I haven’t even seen yet any mid- and high price-range Chinese dash cameras based on capacitor ( 50-150 USD price range ). So for G1W-C developers being budget dash camera it is well made decision to start producing dash camera that can be affordable and at the same time with good specifications and performance.

Pros / cons of capacitor VS battery in dash camera.

Battery based dash cams has been reported having problems working in hot countries, due to battery overheating or even exploding. Many manufacturers advertise having battery in dash cam as positive thing, – you can record videos even without external power source, – yes that’s true, but let’s think in real life we all have mobile phones these days, so we can use them to record footage outside the car if needed. Most battery based dash camera will record around 20-30 minutes if fully charged and this is when they are new. ( latest Mobius and Innovv can record about 1h +/- ). After some period batteries lose their memory ( capacity ) and you are lucky if you can record few minutes footage. After some period of use batteries in many cases can die, so you end up in situation where your dash camera will not save last video file which is in most accidences is the most important video footage you want to keep as an evidence.

With Capacitor based dash cameras there are almost no worries with overheating issue, no exploding batteries, no risk of last file not saved. The only drawback with capacitor based dash cameras is that you can not record footage without external power.
