Frequently Asked Questions
How many Wh is 2,000,000 mAh?
2,000,000 mAh equals 7,400 Wh at 3.7V (Li-ion nominal voltage). The exact Wh depends on the battery voltage: Wh = mAh × V / 1,000.
How do I convert 2,000,000 mAh to Wh?
Multiply 2,000,000 by the battery voltage, then divide by 1,000. At 3.7V: 2,000,000 × 3.7 / 1,000 = 7,400 Wh.
Is 2,000,000 mAh allowed on a plane?
At 3.7V, 2,000,000 mAh = 7,400 Wh. Airlines allow lithium batteries up to 100 Wh in carry-on luggage. Batteries between 100–160 Wh require airline approval. Batteries over 160 Wh are prohibited on passenger aircraft.
Formula: Wh = mAh × V / 1,000. Results assume nominal battery voltage.
