I was outside for nearly five hours, volume mostly at halfway, the built-in battery still showed two lights when we packed up, not bad at all.Packaging was the usual foam, though at least my DIY scissors got a workout. Everything was recyclable so it's hard to complain.Big clear knobs, sturdy handle, rich natural tone, and proper portability, this amp feels solidly good value. I’m keeping it in the camper van for the next hill-top sunset session and I cannot wait! ### ⭐⭐⭐⭐ Good amp , portable sound and power . *by on Reviewed in the United Kingdom 27 June 2026* I plan on going busking after a knee operation so haven’t really put it through its paces, but so far very pleased , the sound is good and three inputs good , I also have a lead from the back of the amp to power 9v effects , I can put two dynamic mics in and guitar and effects , I have a Sonicake four effects in one and more with Mr Power 9v batteries . So my outdoor portable rig is complete , well pleased . Not sure of volume and how long a full charge will last ? But pleased . ## Frequently Bought Together - Coolmusic Portable Acoustic Guitar Amplifier, For Performers On The Go, Built-in Bluetooth (40W Battery-Powered) - TONOR Dynamic Karaoke Microphone for Singing with 16.4ft/ 5M XLR Cable, Metal Handheld Mic Compatible with Karaoke Machine/Speaker/Amp/Mixer for Karaoke Singing, Speech, Wedding and Outdoor Activity - Microphone Stand Boom with Free Adjustable Clips --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/181255519-portable-40w-battery-powered-acoustic-guitar-amplifier-with-bluetooth-coolmusic](https://www.desertcart.tn/products/181255519-portable-40w-battery-powered-acoustic-guitar-amplifier-with-bluetooth-coolmusic) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
