Good question, but the calculation needs a small correction! The correct Watt-Hour rating is approximately 37Wh, not 50Wh. Here's why: The formula is: Wh = (mAh ÷ 1,000) × Voltage However, you need to use the battery's nominal voltage (typically 3.7V for lithium-ion), not the output voltage (5V). Correct calculation: 10,000mAh ÷ 1,000 = 10Ah 10Ah × 3.7V (nominal battery voltage) = 37Wh Why not 5V? 5V is the USB output voltage after the power bank's internal circuitry converts it The actual lithium-ion battery cells inside operate at 3.7V (nominal) For capacity and airline regulations, you always use the battery's internal voltage (3.7V), not the output voltage Why this matters: For TSA/airline compliance, 37Wh is well under the 100Wh limit for carry-on This is the standard way manufacturers calculate and label power bank capacity So the Energizer MAX 10,000mAh is rated at approximately 37Wh, which makes it very travel-friendly!
Sorry, there was a problem. Please try again later.37wh
Sorry, there was a problem. Please try again later.Dear valued customer, Thank you for the comment. For a 10,000mAh power bank, TennRich currently requires the rated capacity to be at least 6,000mAh, which means the 5V output must be no less than 6,000mAh.
