Third-party reviews

What customers like about CUBOT KingKong ES 3 4G (6GB + 256GB)

  • High durability with IP68 and IP69K ratings for dust, water, and drop resistance
  • Excellent battery life (5100 mAh) that reliably lasts over a full day of typical use
  • Affordable price point, often cited as providing great value for a rugged device
  • Smooth display experience with a 90Hz refresh rate on the 6.56-inch HD+ screen
  • Slimmer and lighter design (12.8 mm thickness) compared to traditional 'brick-like' rugged phones
  • Stock Android 14 operating system without excessive pre-installed bloatware

What customers don't like about CUBOT KingKong ES 3 4G (6GB + 256GB)

  • Lack of a fingerprint scanner for biometric security, relying solely on face unlock or PIN
  • Poor speaker placement on the back panel, which can lead to muffled audio during use
  • Mediocre camera performance, particularly in low-light conditions and with moving objects
  • No NFC support for contactless payments in several regional versions
  • Performance lags under heavy loads due to the entry-level Unisoc T606 processor
  • Low display resolution (720 x 1612 HD+) and limited brightness in direct sunlight

Verdict

The CUBOT KingKong ES 3 is a rugged 4G smartphone built for durability and extended outdoor use, featuring IP68/IP69K and MIL-STD-810H certifications for water, dust, and shock resistance, a massive 10,200mAh battery with 33W fast charging, and a 6.74-inch HD+ 90Hz display. It is powered by the Unisoc T615 octa-core processor with 6GB of physical RAM (16GB extended) and 256GB of expandable storage, and runs on Android 15. The main pros include its extremely long multi-day battery life, durable yet relatively slim design for a rugged phone, expandable memory, and NFC support. Key cons are the 720p display resolution which some find low for its size, mediocre camera performance especially in low light, the absence of a fingerprint scanner (relying on face unlock), only moderately fast internet speeds with no 5G support, slow memory, and no guarantee of future software updates.
