70mai’s 4K dashcam range, led by the Dash Cam 4K A810, was part of the company’s Amazon Prime Day promotion, but the discount is not a guaranteed live offer today. In a June 2026 announcement distributed through EIN Presswire, 70mai advertised savings of up to 47% across four selected dashcams, including the A810 Lite. That figure was a maximum across selected models, not a saving on every camera. Amazon’s Prime Big Deal Days 2026 had also already ended by 5 October, according to TechRadar. This guide covers what the A810 is, what to verify before buying, and what to budget for beyond the camera.
Is the 70mai Prime Day deal still available?
Nothing we can point to establishes a current A810 price or sale on 7 October 2026. The only discount evidence is 70mai’s June 2026 announcement, which covered selected models, with “up to 47%” as its headline figure. Prices, stock and bundles vary by country and by Amazon storefront, so treat any discount as unconfirmed until you see it on your own regional listing.

Before you buy, check:
- The exact model. The A810 and the A810 Lite are different products. The promotion named the Lite, so a deal on one does not apply to the other.
- The configuration. Is it the front camera alone, or a bundle with the rear camera?
- The strike-through price. Compare the “was” price with what the camera has recently cost, not just with the list price.
- The deal end time. Amazon countdown timers are shown on the listing itself.
- Included extras. Check whether a memory card or hardwire kit is in the box.
What the 70mai Dash Cam 4K A810 offers
These are manufacturer specifications from 70mai’s US A810 product page. We have not tested the camera, so they describe what 70mai claims, not measured performance.

| Feature | 70mai’s stated spec |
|---|---|
| Front video | 3840×2160 (4K) with HDR |
| Rear video | 1080P HDR, in the dual-channel setup |
| Sensor | Sony STARVIS 2 IMX678 |
| Lens | 150° field of view, F1.8 aperture |
| Positioning | Built-in GPS |
| Screen | 3-inch display |
| Optional connectivity | 4G via the UP04 hardwire kit, in listed regions only |
The practical takeaway is that the 4K applies to the front camera. In a dual-channel setup, the rear camera records at 1080P.

Choosing between A810 variants
If the sale lists more than one 70mai 4K model, compare these points rather than the headline discount:
- Front-only versus front-plus-rear, and each camera’s resolution.
- The sensor used.
- Parking-mode power requirements, which usually mean a hardwire kit.
- Whether optional 4G is available in your country.
- Included storage.
- The total price after the accessories you need.
We have no evidence to rank the A810 against competing brands on value, so the comparison above is about checking what you are actually getting.

The memory card you will need
70mai’s support page for the A810 says 4K recording needs a high-speed card and recommends one rated U3 or above. It gives 70mai, Longsys, Samsung, SanDisk and Kingston as examples of suitable brands. Capacity and compatibility can differ between variants, so check the exact model’s guidance before choosing a size. If the listing does not include a card, add one to your budget.

Hardwire kit and 4G: check your country
Parking-style recording typically depends on a continuous power feed, which is what a hardwire kit provides. 70mai lists the optional UP04 4G hardwire kit as supported only in certain countries and areas, including listed parts of Europe and Southeast Asia. Do not assume it works where you live. Confirm support on 70mai’s product page for your country, and decide whether you will fit it yourself or pay for professional installation.

How to judge the real saving
- Open the listing for your country’s Amazon storefront and confirm the exact model name and bundle.
- Note the current price and any displayed deal end time.
- Add the cost of a U3-or-higher microSD card if none is included.
- Add the hardwire kit or installation cost if you want continuous power.
- Compare the total with the same configuration elsewhere, such as 70mai’s own store, before treating it as a bargain.
If the A810 is not discounted when you look, the Lite variant or a later 70mai promotion may be worth waiting for. We cannot say when the next one will be.
