The world’s largest battery-powered phones: How long does it take to charge?

Battery capacity is crucial in smartphones, determining their usability in the realm. The Energizer Power Max P18K Pop and JCB Toughphone Max are contenders. They could be the world’s largest battery-powered phone. In this article, we’ll explore the charging capabilities of these devices. We will focus on the Toughphone Max. The Toughphone Max has an impressive 12,200 mAh battery. Some smartphones have charging speeds of 240W. But they are too fast to fill a 5000 mAh battery. How fast would it be to fill a 12000 mAh battery?

The Energizer  Power Max P18K Pop

The Energizer Power Max P18K Pop boasts a massive 18,000 mAh battery, promising 200 hours of video playback or an astounding 50 days of standby time. Despite its impressive battery life, the handset’s charging speed falls short of its capacity. Although equipped with fast charging technology, it takes approximately eight to nine hours to fully charge the device.

Unfortunately, the Power Max P18K Pop never made it to the market; it was canceled before release. Consequently, we turn our attention to the JCB Toughphone Max, which offers the largest available battery capacity.

If the Energizer Power Max P18K Pop, equipped with an 18,000 mAh battery, had a charging speed of 240W, the estimated charging time could be calculated using the formula: Charging Time (hours) ≈ Battery Capacity (mAh) / Charging Current (mA) × Charging Voltage (V) / Charging Power (W). Assuming a common charging current of 2000 mA, the calculation yields a charging time of approximately 56 minutes. This implies that with an exceptionally high charging power of 240W, the Power Max P18K Pop could be charged rapidly, making it an efficient choice for users seeking quick replenishment of their device’s battery.

JCB Toughphone Max

The Toughphone Max features a formidable 12,200 mAh battery, providing users with over 30 days of standby time or more than 20 hours of continuous video playback. Notably, the Toughphone Max supports 18W fast charging, adding convenience to its impressive battery capacity.

Charging Time Calculation

To calculate the charging time for the Toughphone Max, we need to assume the charging current, typically known as the output current of the charger. Let’s consider a common charging current value of 2000 mA or 2A.

The formula for charging time is approximately equal to Battery Capacity (mAh) divided by Charging Current (mA), multiplied by Charging Voltage (V), and then divided by Charging Power (W) (Charging Time (hours) ≈ Battery Capacity (mAh) / Charging Current (mA) × Charging Voltage (V) / Charging Power (W))

Putting in the values, the charging time can be estimated as 12,000 mAh divided by 2,000 mA, multiplied by 5 V, and divided by 18 W (12,000 mAh / 2,000 mA × 5 V / 18 W).

Therefore, the charging time for a 12,200 mAh battery, charging from 0 to 100 using an 18W charging adapter, is approximately 6.94 hours.

If the JCB Toughphone Max, equipped with a 12,000 mAh battery, had a charging speed of 240W, we can estimate its charging time using the formula: Charging Time (hours) ≈ Battery Capacity (mAh) / Charging Current (mA) × Charging Voltage (V) / Charging Power (W). Assuming a common charging current of 2000 mA, the calculation yields a charging time of approximately 37 minutes. This suggests that with an impressive 240W charging capability, the Toughphone Max could be charged swiftly, making it a practical choice for users looking for a quick turnaround in recharging their device’s battery.

Conclusion

In conclusion, the JCB Toughphone Max, equipped with a substantial 12,200 mAh battery and 18W fast charging, takes approximately 7 hours to fully charge. While this duration may seem lengthy, considering the enormous battery capacity. If you charge Toughphone Max while sleeping at night, you can use it for 3 to 4 days without charging.
