70mai A810 Lite: problems, parts and running costs

Checked: 2026-10-16

Summary

The most common complaints are the front frame rate dropping from 30fps to 24 or 25fps when both cameras record, and a rattle from a supercapacitor that is not secured to the board on some units. Ongoing cost is a microSD card you replace periodically; adding the optional 4G cloud means a $65.99 UP05 kit plus $53.99 to $107.99 a year in data plans. At or below $100 it is a strong budget pick; the $149.99 MSRP is fair, and above $150 the A810S is the better buy.

Common problems and fixes

Frame-rate drop in dual-channel mode — the most common functional complaint: the front records 30fps on its own but falls to 24fps (60Hz) or 25fps (50Hz) with the rear connected. It is a limitation of the GC8613 platform, not a defect, so there is no fix beyond recording single-channel. [1][2][5][6]
Supercapacitor rattle — a buzzing rattle on some units because the supercapacitor is not physically secured to the board; 70mai has acknowledged it as a design issue and no source settles whether it is universal or unit-by-unit. The 12-month US warranty covers hardware defects with repair or replacement. [5][11][16]
Rear camera quality — the RC21’s 1080p footage is acceptable by day but noticeably weaker than the front at night, and it has no HDR. Nothing to fix; it is the budget trade-off. [5][6][9]
Cheap build quality — DashCamTalk called it “quite cheap”; a materials critique, not a measured failure rate. [5]
Voice control reliability — described as “spotty”; no workaround reported. [10]
Low audio level — the measured audio recording level is very low; no fix reported. [5]

Parts and consumables

Mount and adhesive stickers — spare mounts and adhesive stickers for the A810 are sold on the 70mai EU store; no US parts store was found. [12]
UP05 4G hardwire kit — $65.99 (70mai official store blog, 2026); adds 4G LTE cloud, parking surveillance with cellular alerts and a SIM slot, and is also required for parking modes. [3]

Yearly running cost

With the 4G cloud, add the one-time $65.99 UP05 kit and a data plan at $53.99 a year (Standard) or $107.99 a year (Premium) [3]. No annual electricity figure is published.

When it is a good buy

At or below $100 — strong budget pick: native 4K front, HDR, supercapacitor, GPS, Wi-Fi 6, optional 4G, retained screen. [5]
$101–130 — still good value, especially if 4G connectivity is the priority.
$131–150 — fair; the $149.99 MSRP for the front + rear + 64GB bundle (70mai official store, 2026) sits here. At this level compare the A810S. [2][3]
Above $150 — weak value unless the compact size or the 4G option is the point; the A810S or T800 become better-rounded alternatives.
DashCamTalk’s data sheet lists $89.99 (May 2026), which may reflect a sale or a different bundle [14]; the UK bundle is £129.99 RRP, £99.99 with a voucher (Bedford Today, 2026-10) [13].
Alternatives: the A810S (Sony STARVIS 2, 30fps dual-channel, AI motion detection, ADAS) is the better choice once the budget stretches past $130–150; the A800SE uses the same GC8613 sensor but has no 4G support and is the better choice when cloud alerts are not needed. [2][4][5]
