Deal | 70mai's new tried-and-tested 4K dashcam (with rear camera and SD card) gets a huge 40% Amazon discount

Amazon has just introduced a limited-time deal on the 70mai Dash Cam 4K A810 Lite dual-channel bundle, cutting the price to $89.95. Pushed as a 40 percent discount from its standard 149.99 dollar list price, the promotional package bundles the main 4K front-facing shooter, an RC21 1080p rearview companion camera, and an included 64 GB microSD card to handle immediate storage needs. The deal has already gained traction, tracking over 2,000 units purchased within the past month alone (on Amazon, at least).

Our extensive hands-on testing confirmed that the front-facing sensor gets you excellent daytime clarity and respectable exposure mapping on unlit roads after dark. Moving past traditional, volatile lithium-ion batteries that come with structural risks (especially in summer heat), 70mai equips this chassis with a durable, heat-resistant supercapacitor rated to withstand cabin environments up to 85°C. For quick and seamless data offloading, the device utilizes dual-band Wi-Fi 6 to accelerate large video file transfers directly to a smartphone app.

However, hitting this sub-100 dollar threshold involves real-world concessions. Activating dual-channel mode forces the front recording speed to drop from a fluid 30 frames per second down to 24 or 25 frames per second, which renders slight motion blur on fast-moving highway traffic. Additionally, while the front camera maintains clean target exposure in low light, the secondary 1080p rear window camera struggles much more under dark conditions, suffering from intense headlight glare and digital noise. 

Regardless, for buyers looking for an accessible, multi-lens surveillance system with robust thermal resilience, this discount is a great entry point, especially considering that it's still a relatively newer model.
