Bolanle PH1 PRO In-Ear Monitor Amplifier 25H Battery

The Bolanle PH1 PRO is a pocketable in-ear monitor amplifier with a built-in 1000mAh battery that delivers up to 25 hours of reliable playtime and professional XLR/TRS connectivity for live and studio use.

Designed for working musicians, the PH1 PRO replaces disposable battery amps with a rugged aluminum body, versatile inputs, and a USB-C fast charge system. It gives keyboardists, drummers, guitarists, and sound techs dependable personal monitoring without bulk, using a balanced XLR input, 1/4" TRS input, and a 3.5mm headphone output. The compact footprint and belt clip make it stage-ready while the long battery life reduces operating costs and setup hassle.

How long will the battery last during rehearsals and gigs?

The PH1 PRO uses a 1000mAh rechargeable battery rated for around 25 hours of continuous playback on a single charge, so it typically covers multiple shows or a full weekend of performances. A built-in battery indicator provides real-time remaining charge so you can plan charging between sets.

• 1000mAh internal battery for extended runtime
• Approx. 25 hours per full charge under normal use
• USB-C fast charge replenishes battery in about 2.5 hours
• On-unit battery level indicator for easy monitoring

What connections will it integrate with on stage or in the studio?

The PH1 PRO supports balanced XLR input for clean mixer feeds, a 1/4" TRS input for keyboards or DI boxes, and a 3.5mm headphone output for any in-ear monitors. A stereo/mono switch lets you choose true stereo monitoring or a summed mono mix depending on your rig or stage placement.

• XLR balanced input for low-noise signals from mixers
• 1/4" TRS input for instruments and line-level gear
• 3.5mm output compatible with universal and custom IEMs
• Stereo/mono switch to tailor your monitoring mix

Is the PH1 PRO durable and easy to wear during performances?

The amp is built from an all-metal aluminum chassis that stands up to road use and stage accidents while weighing only about 3.5 ounces. It includes an integrated belt clip so you can mount it on a strap, belt, or stand, keeping the unit secure and out of the way while you play.

• All-metal housing for rugged stage durability
• Compact dimensions (about 4.3" × 1.2" × 1.0") and lightweight design
• Sturdy integrated belt clip for hands-free wear
• Pocket or gig-bag friendly size for easy transport

How does it save money compared with battery-powered amps?

By replacing disposable AAA batteries with an internal rechargeable cell, the PH1 PRO reduces recurring battery expenses and environmental waste. For regular gigging musicians, the claimed savings pay back the amp cost quickly, while USB-C charging keeps operating costs minimal.

• Eliminates frequent AAA battery purchases
• Estimated savings versus disposable batteries over months
• Fast recharge minimizes downtime between shows
• Lower long-term operating costs for touring musicians
