Frequently Asked Questions
How many Wh is 30,900 mAh?
30,900 mAh equals 114.33 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 30,900 mAh to Wh?
Multiply 30,900 by the battery voltage, then divide by 1,000. At 3.7V: 30,900 × 3.7 / 1,000 = 114.33 Wh.
Is 30,900 mAh allowed on a plane?
At 3.7V, 30,900 mAh = 114.33 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.
