Powerbank to iPhone 16e

ChatGPT says:

To estimate how large a power bank you need, you must account for charging losses. A power bank rated at 10,000 mAh does not deliver the full 10,000 mAh to the phone; typically, only about 60–75% of the advertised capacity is usable after voltage conversion and efficiency losses.

Approximate number of full iPhone 16e charges:

A quick rule of thumb:

Required power bank capacity ≈ Number of desired full charges × 4,005 mAh ÷ 0.7

Examples:

• 2 full charges → about 11,500 mAh
• 3 full charges → about 17,200 mAh
• 5 full charges → about 28,600 mAh

So if your goal is to recharge an iPhone 16e multiple times, a 20,000 mAh power bank is usually the sweet spot, providing roughly 3½–4 full charges in real-world use.
