High-capacity recorder for lectures and meetings

The Aiworth E36 provides 136 GB of combined storage, pairing 8 GB of internal flash with a supplied 128 GB card. It captures MP3 audio at up to 1536 kbps using dual microphones. The device is aimed at students, journalists and professionals who need long, clear recordings without frequent file transfers.

45-hour battery life and low power draw

A built-in 800 mAh lithium-polymer cell delivers up to 45 hours of continuous recording on a single charge. The battery weighs 14.8 grams and stores 2.96 Wh of energy. Voice-activated recording extends practical usage by pausing during silence, reducing both power consumption and storage use during lectures or meetings.

Password protection and variable-speed playback

A three-digit power-on password offers 8000 possible combinations; after three failed attempts the unit shuts down automatically. The recorder also functions as an MP3 player with variable-speed playback, allowing faster review of captured material. A 3.5 mm headphone jack enables private listening.

Questions about this item

How do I insert the 128 GB memory card and which slot do I use?

The 128 GB card comes pre-installed in the TF slot; if you ever replace it, power off the recorder, open the card cover, slide the new microSD card in until it clicks, then set Menu → Save position → TF so the TF icon appears.

What part will need replacement first and how do I know?

The built-in 800 mAh lithium-polymer cell is the only consumable; when a full charge no longer delivers roughly 45 hours of recording or the battery swells, the unit must be sent for service because the cell is not user-replaceable.

At what point does continuous recording stop on a single charge?

The recorder stops after about 45 hours of non-stop recording because the 2.96 Wh battery is depleted; voice-activated mode extends this by pausing during silence.
