Key Differences
Marshall's 30-hour battery beats Anker's 20-hour figure by a meaningful margin, while Anker's larger physical size and handle suggest a design more oriented toward being carried to a specific outdoor spot and set down for extended group listening, versus the Emberton III's more grab-and-go portable design. Marshall's recognizable design language is also a genuine factor for buyers who specifically want that amp-inspired look.
