AGPTEK A02S 16GB MP3 Player - 70H Playback, Lossless

This pocket-sized music player combines a long-lasting battery, broad codec compatibility, and a sport-friendly design so you can listen longer without carrying a phone. With a simple button interface and drag-and-drop file transfer, the A02S focuses on straightforward, reliable playback for workouts, commutes, and travel.

How long will the battery last during regular use?

The built-in 420mAh lithium polymer battery delivers up to about 70 hours of continuous playback on a full charge. Charging from empty takes roughly 2–3 hours via the included USB cable, so you can quickly top up between sessions.

• Up to 70 hours playback per full charge
• 2–3 hours USB charging time
• Low-power hardware for extended standby and play

What audio formats and sound quality can I expect?

The A02S plays a wide range of formats — including MP3, WMA, OGG, WAV, APE, FLAC, AAC-LC, and ACELP — so it handles both lossy and lossless files for clearer, more detailed music. Note that APE and FLAC have specific sampling requirements, and the player does not natively support iTunes-protected audiobooks.

• Supports common lossy and lossless formats for high-fidelity playback
• APE and FLAC supported at 8–48kHz sampling (1000Kbps requirement)
• Not compatible with DRM/iTunes-protected audiobook formats

Can I carry this for workouts and how do I transfer music?

Designed for sports, the A02S is palm-sized and lightweight so it fits in a pocket, wallet, or armband without weighing you down. Files transfer painlessly: connect the player to a computer via USB and drag-and-drop music folders — no special software required.

• Small, lightweight housing ideal for running and training
• Classic tactile buttons for easy control during activity
• Plug-and-play USB file transfer; works with car AUX inputs

How much music can I store and is expansion available?

Internal storage is 16GB — enough for roughly 4,000 average MP3 tracks — and the unit accepts a microSD card up to 128GB for large libraries. Volume and playback controls are physical buttons; hold the VOL button to enter volume adjust mode, then use left/right to change levels.

• 16GB built-in memory (~4,000 average MP3 tracks)
• microSD expansion up to 128GB for thousands more songs
