Is the 0.7″ thickness real? Other 20,000mAh power banks are around 1.2″ thick.

Yes. This power bank uses custom ultra-thin cells to cut volume at the source, safe & reliable. The unibody molded shell eliminates assembly gaps, reducing thickness even more.

Does it support 45W PD charging for laptops?

Yes, it supports emergency top-up for laptops. While 45W may not fully power a laptop under heavy load, it’s perfect for keeping your slim laptop running during meetings, travel, or other urgent situations.

Curious why your power bank doesn’t charge as many times as you expect?

Typically, an external battery delivers 60%–70% of its capacity to other devices. The remaining 30%–40% is lost to circuit heat and voltage conversion. So a fully charged Neoseek 20000mAh power bank gives you about 12000–14000mAh of usable power.

How to estimate how many charges you’ll get?

Use the industry-standard formula:

(Power bank capacity × 65%) ÷ Device battery capacity = Number of charges

Example:

(20,000mAh × 0.65) ÷ 3,279mAh (iPhone 14) ≈ 4.0 charges

Is this power bank heavy?

For a 20000mAh power bank – no, it’s normal weight.

For a “palm-sized” battery – yes, it will feel heavier.

Think of it this way:

Same weight as others, but much thinner. We took out the bulk, not the battery cells.
