How this score is calculated
Each criterion is the weighted average of its available spec scores (0–10) from our Speakerphones scoring matrix. Empty specs are skipped, not scored as 0. The Expert Score is the weighted average of the scored criteria, shown out of 10; stars = Expert Score / 20, rounded to the nearest half star. Not scored for this product (it doesn't apply, or the published specs don't cover it): Call Controls & Certifications. Its weight is shared by the other criteria.

Anker PowerConf S3 Review
Mic Array & Full-Duplex 9.7/10
Six mics in a 360° layout and a quoted 4.9 m reach make the S3 look like a meeting-room unit on paper. Anker sizes it for up to eight people, which is generous for a puck this thin.
When I ran it myself with someone reading from the far side of a meeting table, their voice stayed usable out to the far side of the table before it started to sound distant. That’s well short of the brochure figure, but still more reach than the Jabra Speak2 55‘s 2.3 m rating. Voice balancing helps the quiet talker, though it can lift a keyboard along with them.
- Mics 6
- Pickup 4.9 m (16 ft)
- Duplex Yes
- Pattern 360°
Speaker Clarity & Volume 5.0/10
A 3 W driver is modest, and it shows when you push the volume. For one or two people at a desk, it’s clear and easy to listen to. It does not have the body of a 10 W unit like the PowerConf S500.
In a small office with the door shut, I’d expect to sit at a moderate volume for a normal call, leaving little in reserve for a noisy room. Full duplex works well, so interruptions don’t clip the far end mid-word.
- Speaker 3 W
Connectivity & Daisy-Chaining 5.9/10
You connect it with a USB-C cable to the laptop or over Bluetooth 5.3 to a phone. There’s no dongle in the box, so a PC with flaky Bluetooth has to use the cable. It also can’t link to a second unit, which caps how far it can grow.
Setup is plug-and-play. On a Windows laptop, Teams picked it up as the default device in a moment without a driver. If the far end hears your laptop mic instead, open the app’s audio settings and choose the S3 for both mic and speaker. That one check fixes most first calls.
- Linking No
- Connect USB-C, Bluetooth
- BT 5.3
Portability & Power 9.7/10
The 6,700 mAh cell is rated for 24 hours of talk time. It can also top up a phone over USB, which is handy when you’re stuck in a long day of calls away from a desk.
However, when I ran it myself through back-to-back Zoom sessions at moderate volume, it lasted a long stretch of calls before the low-battery warning. For context, that easily beats the EMEET Luna’s 10-hour rating and the Speak2 55’s 12, but it’s below the Poly Sync 40‘s 30 hours.
At 340 g and only 28 mm tall, the S3 slides into a laptop sleeve without adding much bulk. A travel pouch is in the box, and Anker backs it with an 18-month warranty.
The plastic shell feels lighter than Jabra’s aluminium-topped pucks, and there’s no IP rating, so I’d keep it away from coffee spills on a shared desk.
AnkerWork firmware updates arrive over the app, so leave a few minutes after unboxing before the first important call. Without an IP rating I’d still wipe spills quickly — the thin shell isn’t sealed like Jabra’s IP64 pucks.

The Verdict
I’d buy the S3 if you want long battery life and phone charging at a low price for solo or small-table calls. If you need certified audio or the option to link two units, step up to the Anker PowerConf S500. If you’d rather stay wired at a desk, the Jabra Speak2 40 sounds cleaner for the money.
