Magnetic Wireless Power Banks Explained For Buyers

Magnetic power banks are the fastest-moving part of this catalogue. They are also the ones buyers most often mis-specify, because the magnet and the wireless charging are two separate things.

The magnet solves alignment, not speed

Wireless charging only reaches its rated output when the coils in the pack and the phone line up. On a flat pad the user has to find that position. A magnet array holds it automatically, which is why magnetic packs feel faster than pads rated the same.

Wireless output and wired output are different numbers

FL-PB004 is rated 22.5W wired and 15W wireless. FL-FB031 is 20W wired and 15W wireless. FL-FB042 and FL-FB043 are built in two versions - one with a 5W pad, one with a 15W pad. Listing the wired figure next to a wireless product is the most common error we see on retail pages.

Cases are the usual failure

A thick, metal-backed or heavily armoured case weakens the magnetic hold and puts distance between the coils. Thin cases and magnet-compatible cases are fine. This is worth saying on your own product page, because it is the most common support question.

Where capacity fits

The magnetic range runs from 10000mAh - FL-FB031, FL-PB004, FL-FB042 - to 20000mAh on FL-FB043 and FL-PB002. The larger packs are noticeably thicker at 29 and 32mm, which is the cell, not the magnet.

What To Take Away

• Publish the wireless output figure separately from the wired one.
• Tell end users that thick or metal cases break the hold.
• The 5W and 15W builds of FL-FB042 and FL-FB043 share a body - check which one you are quoting.
• A magnet does not make a pack faster; it makes the rated speed achievable.
