Comparing Ausom K20 and K20 Pro chargers

The versions in this family deliver the same final voltage of 54.6V. The charging current, the casing, and the estimated duration distinguish the products. The 2A is suitable for standard charging, the 4A for fast charging, and the 5A for shorter charging times.

Ausom K20 / Laluz 2 – 13.5 Ah

• 2A standard: ≈ 6h 45m
• 4A fast: ≈ 3h 15m
• 5A ultra-fast: ≈ 2h 30m

Ausom K20 Pro – 18 Ah

• 2A standard: ≈ 9h
• 4A fast: ≈ 4h 30m
• 5A ultra-fast: ≈ 3h 30m

These times are estimates for a 0 to 100% charge with a single charger, calculated by dividing the battery capacity in Ah by the charging current in A, then rounding down to the nearest quarter hour. The starting level, temperature, and battery condition will cause the actual time to vary.
