The Aroma AG-04 is a compact, rechargeable 5-watt mini amplifier crafted for electric guitar practice and portable play. It features dual 1.75-inch full-range speakers, analog tone shaping (clean and overdrive modes), and controls for gain, tone, and master volume. Wireless Bluetooth (v5.3) lets you stream backing tracks or use the amp as a speaker, while a headphone output supports silent practice (muting the speakers when plugged in). With a built-in 3.7 V / 2000 mA lithium battery, it offers up to ~7 hours of use on a full charge (via Type-C USB). Its small footprint (125 × 65 × 88 mm) and lightweight design (~363 g) make it ideal for home jamming, travel, or couch sessions.
