Charging time is determined by the current you set. For example, to charge a 50000mAh (50Ah) battery pack, if set to 40A current, the theoretical full charge time is about 1.25 hours (not considering efficiency loss).\u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"faq-item\"\u003e\n                \u003cp class=\"faq-q\"\u003eQ2: Can it be used on a standard 220V home outlet?

At 220V voltage, a single channel of this charger can reach a maximum of 2000W, and both channels can work simultaneously at a maximum of 4000W (2000W per channel). When using, ensure the outlet, power strip, and circuit can handle the corresponding power (4000W is approximately 18A current). It is recommended to use a dedicated 16A or higher outlet or industrial power strip, and use an independent circuit to ensure safety.\u003c\/p\u003e\n            \u003c\/div\u003e\n            \u003cdiv class=\"faq-item\"\u003e\n                \u003cp class=\"faq-q\"\u003eQ3: The charger fan is noisy\/noticeably hot.
