The Obriy device consumes up to 3 A during active charging and about 1.5 A when fully charged. For stable 24/7 operation, it is critical to choose the correct cable and power adapter, as they determine the charging speed and safety.
Cable
The main factor in efficient charging is a high-quality cable. We recommend certified cables (for example, Baseus) that support 3 A current, fast charging via the modern USB-PD standard (Power Delivery — adaptive voltage and current adjustment for fast and safe charging), and 10–15 W power.
Using uncertified or low-quality cables leads to a drop in current: a poor cable may deliver only 0.7 A instead of 3 A, which significantly slows down charging and creates additional thermal stress on the battery.
If another cable is used, be sure to check its ability to deliver the required current using a tester such as FNIRSI FNB58 (in the carousel we showed how to determine which cable is better for charging).
For Obriy, the minimum acceptable current is 2.5 A.
The optimal cable length is up to 0.5 m, as longer cables cause voltage drop and reduced charging efficiency.
Power Supply / Adapter
A quality adapter must stably provide 5 V / 3 A. Under load, the voltage should not drop significantly. “Smart” chargers may automatically increase the voltage to about 5.2 V to compensate for losses in the cable.
For safe and efficient charging, we recommend:
- using certified adapters or those recommended by us;
- avoiding cheap chargers from unknown manufacturers, which often do not deliver the claimed current;
- regularly checking the condition of cables and connectors — damaged contacts reduce efficiency and may damage the device;
- charging at room temperature whenever possible;
- avoiding direct sunlight and overheating.
Almost any power bank that provides stable 5 V output is also suitable for charging. If the device operates from the charger and the battery does not discharge, it means the power supply is working correctly.
