It takes approximately 3 hours to fully charge a Hammerhead Karoo 2 from a completely depleted state.
The Karoo 2, a popular GPS cycling computer, features a 2500mAh battery designed to power your rides. Understanding its charging characteristics is crucial for efficient use.
Karoo 2 Charging Time Overview
While a full charge takes around three hours, the device supports faster charging for the initial power-up, allowing you to get going quicker.
- Full Charge: Expect the Karoo 2 to reach a full 100% charge in about 3 hours when starting from a completely flat battery. This duration is notably longer compared to some other smaller electronic devices.
- Quick Boost (0-30%): For those times when you need to quickly add some juice, the Karoo 2 can charge from 0% to approximately 30% in just about 30 minutes. This rapid initial charge is facilitated by its charging protocol.
Technical Charging Specifications
The Karoo 2 has specific requirements and capabilities regarding its power input:
- Battery Capacity: The device is equipped with a 2500mAh battery.
- Voltage Compatibility: The Karoo 2 does not support charging over 5 volts (5V). Using chargers that exceed this voltage could potentially damage the unit.
- Current Flow: The maximum current flow supported is 2.5 Amps (2.5A). It's important to note that this higher current is primarily utilized during the initial charging phase (0-30%) to achieve the faster charge time. After this initial period, the current flow typically reduces to protect the battery and ensure a healthy charge cycle.
To ensure optimal charging performance and battery longevity, it's recommended to use chargers that adhere to these specifications. Using a standard USB wall adapter (often 5V/1A or 5V/2A) should work, but a charger capable of providing 2.5A will maximize the speed of the initial charge.
