Our take on the MERILER Portable Rechargeable Air Conditioner 2026 Upgrade

The MERILER Portable Rechargeable Air Conditioner is a small personal cooling unit with a 2000mAh battery, three fan speeds and a mist mode. It weighs 1.59 lb and stands about 11.8 inches tall, so it fits on a desk or nightstand. It is not a real air conditioner: it blows air over an ice-crystal pack and adds mist, with no compressor or refrigerant. At $40.99 at Walmart as of November 8, 2026, it is the only new price listed, so there is no recent range to compare against.
