Eufy Security S220 SoloCam: problems, parts and running costs

Checked: 2026-10-11

Summary

The most reported problem with the S220 is severe battery drain after firmware or app updates, with solar charging failures a close second. There is no subscription and no mandatory recurring costs; the only optional spend is an external solar panel at $99.95. It is strong value under $80 and weak above $100, where eufy’s own S230 becomes the better choice.

Common problems and fixes

Severe battery drain after firmware or app updates — multiple Reddit owners report sudden 45-50% daily drain, and one owner had three S220 cameras all draining more than 50% in less than a day after an app update; owners found help in eufy’s troubleshooting guides and sometimes a factory reset, and B&H lists a 1-year limited manufacturer warranty. [3][7][8][13]
Solar charging failures — owners report the panel not charging (stuck at 96%, or not charging at all); one owner associated firmware 3.3.2.3 with charging issues, and a factory reset (five sync button presses) sometimes resolves it. [9][10]
False motion triggers — cars, trees and birds can trigger alerts despite AI human detection; the camera supports up to 2 activity zones to narrow detection. [1][2][5]
Battery is not user-replaceable — if the battery fails, the entire camera must be serviced or replaced. [2]
App complexity — some owners find the eufy Security app “too busy” with community features and ads, preferring a more streamlined interface. [6]

Parts and consumables

Integrated 0.9 W solar panel — included; it collects 200-400 mAh per day in optimal sunlight while the camera consumes 100-130 mAh per day, so about 3 hours of direct sunlight daily should keep it running indefinitely; it cannot be used at the same time as an external panel. [1][2]
External eufy Solar Panel (3W) — optional add-on for $99.95 at eufy (2026) if the integrated panel is insufficient. [14]
6500 mAh battery — not user-replaceable; a failed battery means servicing or replacing the whole camera. [2]
8 GB eMMC storage — built in, not removable and not expandable via microSD; when full, the camera overwrites the oldest recordings. [1][2]

Yearly running cost

There are no mandatory recurring costs: no subscription is required or available for cloud storage, and there are no consumables — the integrated solar panel is included and USB charging (about 5 hours) costs only household electricity. The only optional spend is the external eufy Solar Panel (3W) at $99.95 (eufy, 2026), a one-time purchase for owners whose sunlight is insufficient. A typical owner spends $0 a year.

When it is a good buy

eufy US direct lists the single camera at $99.99, a 2-pack at $199.99, a 3-pack at $299.99 and a 4-pack at $399.99. [1]

Best Buy lists the S220 with HomeBase 3 at $179.99. [16]
At $60 or less it is strong value; at $61-80 good value; at $81-100 fair value; above $100 weak value unless the solar-only form factor is the point. [1][2]
Better choice above $100: the S230 (SoloCam S40) at $129.99 direct, which adds color night vision, a spotlight, a larger solar panel and a 4-month battery; the S340 is the alternative for PTZ coverage. [12]
