Ready-to-use power for iPhone 15, 16 and 17 series

This 5000mAh power bank has a built-in USB-C connector so no cable is required. It is designed for iPhone 15, 16 and 17 models as well as Samsung S22 and S23 series phones. The unit weighs 0.2 lbs and measures 3.03 x 1.38 x 0.96 inches, fitting in a pocket or small bag. It suits commuters and travellers who want a compact backup without carrying extra leads.

20W fast charging with dual-voltage input

The pack delivers up to 20W output, taking a compatible phone from 0% to 50% in roughly 30 minutes. Input accepts 110V to 240V, so it works worldwide without a separate converter. In normal use the small form factor stays cool and silent while recharging a handset. A USB-A to USB-C cable is included for recharging the power bank itself.

5000mAh capacity gives roughly half a phone charge

Capacity provides about 0.6 full charges for iPhone 16, 0.65 for iPhone 15 and 0.53 for Galaxy S24. It will not fully recharge a modern flagship from empty, so users needing multiple top-ups should consider a larger bank. The built-in connector does not fit phones inside OtterBox cases, so those owners must remove the case to charge.

Questions about this item

How do I install the built-in USB-C connector on my iPhone 15 without forcing it?

Remove any thick case such as an OtterBox first, then align the fixed USB-C plug with the port and push straight in until it seats — angling the connector is the step people get wrong.

What maintenance or replacement will this 5000mAh power bank need later?

The sealed lithium cell is not user-replaceable; when run-time drops noticeably after many charge cycles the entire unit must be replaced.

What limit shows up first when I use the 20W output continuously?

The 5000mAh capacity depletes after roughly half a phone charge, so runtime ends before thermal throttling becomes an issue.
