# Charger Master vs M Bench

The clearest difference is rating: M Bench at 5.0 against Charger Master's 4.3. M Bench also leads on in-app purchases (none vs 2) and ads (none vs shown). Charger Master's advantage is update cadence (every 10 days vs every 14 months) and review sentiment (27% vs 0%). On price and device support there is nothing between them.

Both are free to download. Charger Master sells 2 one-off in-app purchases. M Bench asks for nothing beyond the download.

M Bench holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Charger Master has 6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 27% of Charger Master's written reviews are positive against 0% of M Bench's, so the app with the better star average is not the one people write more warmly about.

Charger Master ships an update every 10 days, M Bench every 14 months. The most recent releases landed on September 27, 2026 and June 4, 2026 respectively.
