Mission Engineering 529i Power Supply Review - Gigs & Guitars

gigsandguitars.com

While the Mission Engineering 529i Power Supply boasts a sleek design, solid build quality, and a capable 8000mA battery that delivers up to two hours of power, it falters with significant drawbacks. The inability to replace the battery raises concerns about longevity, effectively rendering the unit useless once the battery dies. Additionally, the restriction of charging while in use is a frustrating oversight, limiting flexibility during performances. Despite its well-structured outputs and clean power delivery, these critical flaws overshadow its advantages, making it hard to recommend for those seeking a reliable, long-term solution for their pedalboard needs.
