SLIM POWER BANKS

It Sticks to the Phone. Does That Mean It Charges Wirelessly?

No. A magnet can hold a battery in place while a short cable does the charging. Qi2 models really do charge through the back of the phone.

LISEN Qi2 Ultra Slim

The viral trick is the thickness.

A battery that looks almost like a card makes ordinary power banks suddenly feel enormous. The visual is immediate, even before capacity and heat enter the conversation.

Thin does not mean a full phone charge.

In Macworld's independent test, Anker A1665 took an iPhone 16 Pro from empty to 77%. That is useful evidence because the number is smaller—and more realistic—than a perfect full-charge promise.

Wireless charging trades some energy for convenience and usually creates more heat. Thickness, weight, a stand, and wired speed can matter as much as the 5,000mAh label.

Checked choices

Decide between cable-thin, Qi2-thin, and a built-in stand.

USB-C · current 5,000 mAh model

The magnet holds the battery against the phone, but electricity still travels through the short built-in USB-C cable. It is not a wireless charger.

This fits when

You want the flattest body here and do not mind plugging in a short built-in cable.

Wireless
None. The maker explicitly says this is not wireless charging.

Baseus PicoGo AM31 Mini

5,000 mAh · Qi2 15 W · built-in stand

Snap it onto a compatible phone, open the stand, and the phone can stay upright while it charges. It supports Qi2 wireless charging up to 15 W and USB-C output up to 20 W.

This fits when

You care more about the built-in stand and lower checked marketplace price than having the thinnest battery in a pocket.

Weight
About 4.9 oz / 138 g
What changes or goes missing
  • At 13 mm, it is noticeably thicker than the slim LISEN and Anker models in this comparison.
  • The stand is useful on a desk, but it adds thickness to something that stays attached to the phone.
  • Qi2 charging needs a compatible phone or magnetic case; a charging-only fit is not enough if the coils do not align.
