Of particular interest lately has been battery safety of wearable watch phones as these devices are worn on the wrists of our kids. This article is aimed to give insights to parents on the safety protocol and regulations of myFirst watchphones so they can be at ease of their children’s safety.

Safety Features of myFirst Wearable Watchphones for Kids

1. Overheating Prevention

myFirst Fone’s main board is equipped with two Negative Temperature Coefficient (NTC) sensors, while another NTC sensor is situated directly on the battery’s Protection Circuit Module (PCM). Each sensor serves a distinct function. One NTC on the main board monitors the board’s temperature, regulating the power consumption of the CPU/GPU and screen brightness to maintain an optimal surface temperature for the Watchphone. Another, the charging NTC, ensures the temperature of the charging module remains within safe bounds by controlling current flow.

Additionally, a dedicated NTC sensor on the battery (PCM), monitors the battery’s temperature, even when it’s not charging, since batteries can also generate heat in a non-charging state. If any of these NTC sensors detect potentially harmful high temperatures, the Fone will automatically power off, and charging will also be halted immediately. This setup is crucial for preventing risks associated with excessive heat.

2. Water Exposure

myFirst Fones are designed with water-resistance ratings of IPX7 and IPX8, which offer protection against water at depths up to 1.5 meters for 30 minutes and 2 meters for 30 minutes respectively, further reducing the risk of water-induced battery failure.

By ensuring the SIM card slot is consistently secured and the product is used within its specified waterproof limits, potential hazards linked to water-induced battery malfunction are significantly minimized.

3. Overcharge Protection

myFirst Fones have a built-in overcharge protection mechanism that automatically cuts off charging of the battery when the voltage reaches 4.45V, preventing both battery damage and overcharging.

4. Battery Module Selection and Qualification

To ensure the kids’ watchphone battery safety, myFirst follows a meticulous process of selecting and qualifying battery modules. These batteries undergo comprehensive laboratory tests covering over 40 categories, including overcharge resistance, discharge performance, and thermal stability. This testing protocol aligns with international safety standards and certifications from recognized organizations.

It is important to recognize battery damage indicators and promptly arrange for a battery replacement if necessary to maintain watchphone safety. Additionally, being cautious about physical impacts on battery safety is crucial for ensuring the long-term safety of your child’s watchphone

This certification certifies that the safety standards required for exporting wireless equipment and information processing technology equipment to North America (USA, Canada) for myFirst products are met.

5. Quality Assurance for Mass Production

During each production cycle, myFirst conducts rigorous quality and safety tests on battery samples from every incoming batch of batteries. These tests encompass over twenty categories, including overcharging, penetration, thermal shock, external short circuit, impact testing, and drop testing.

Furthermore, every myFirst Fone is subjected to a 72-hour aging test before shipping. This test involves operating the device under normal conditions to identify potential reliability issues. By carrying out these extensive tests, myFirst provides a safe and reliable product to our kids.
