Power, battery & data usage

Battery & charging

  • Battery type Lithium-ion polymer (non-removable)
  • Capacity 5100mAh
  • Active working time Approx. 11 hours of active captioning (screen on)
  • Charger output 5 V / 3 A (15W wired charging)
  • Charge time Approx. 4 hours from 0–100% with included brick and cable
  • Included cable 3' or 36in (92cm) USB-C to USB-C charging+data

With the included charger, the tablet charges at about 1% every 2 minutes (approximately 0–95% in 3.5 hours; last 5% in ~30 minutes). Roughly 20 minutes of charging provides about 60 minutes of active captioning time.

As with all portable electronics, some battery capacity degradation is normal over years of use.

Internet

  • Offline AI captioning in 18 languages/dialects requires no internet
  • ≥ 1 Mbps up/down for online AI captioning in 81 languages/dialects
  • ≥ 1 Mbps up/down for human remote captioning (audio only, pre-scheduled)
  • ≥ 2–3 Mbps up/down for human remote interpreting (audio+video, pre-scheduled)

Data consumption (per minute)

  • 0 MB/min — offline AI captioning
  • 1 MB/min — online AI captioning (no data used when no audio is detected)
  • 1 MB/min — human remote captioning (audio feed only)
  • 22 MB/min — human remote interpreting/captioning (audio+video feed)

SmartMic specifications

Performance

  • Pickup range Approx. 30ft (9m) from speaker to mic; best accuracy when clipped to clothing
  • Operating range Approx. 100ft (30m); up to 200ft (60m) line-of-sight between SmartMic and tablet
  • Polar pattern Omnidirectional
  • Audio sensitivity 25dB

Bluetooth can travel through solid objects, but more obstacles between the SmartMic and tablet will reduce maximum operating distance. Battery capacity will naturally decline over years of use.

Battery & charging

  • Battery 130mAh non-removable lithium-ion
  • Active working time Approx. 6 hours of active captioning
  • Charging interface USB Type-C
  • Charge time Approx. 1.5 hours from 0–100%
  • Included cable 18in (46cm) USB-A to USB-C, charging only (no data)

15 minutes of charging yields roughly 60 minutes of use.

Hardware & connectivity

  • Dimensions 2.64in × 0.6in × 0.6in (6.7cm × 1.5cm × 1.5cm)
  • Weight 0.6oz (15g)
  • Analog interface 1/8" (3.5mm) TRRS jack
  • Bluetooth Bluetooth 5.0 (A2DP, HFP, SWISS) with 48kHz full-band audio

Battery indicator

On-screen SmartMic battery percentage is shown in 10% increments:

  • 100 = 100–91%
  • 90 = 90–81%
  • 80 = 80–71%
  • 70 = 70–61%
  • 60 = 60–51%
  • 50 = 50–41%
  • 40 = 40–31%
  • 30 = 30–21%
  • 20 = 20–11%
  • 10 = 10–1%
