FL-FB042 Magnetic Wireless Power Bank With Three Built-In Cables
10000mAh magnetic pad plus three captive cables in a 21mm body
FL-FB042 answers the single most common complaint about promotional power banks: the recipient loses the cable. Three cables are built into the 140 x 69 x 21mm body, and the top face is a magnetic wireless pad, so the unit charges a phone four different ways without anything else in the bag.
It is a 10000mAh pack with 2.1A/18W input. Two output builds are available from the same tooling, one with a 5W wireless pad and one rated 22.5W wired with a 15W pad, which lets you place the cheaper build into a giveaway run and the faster build into a retail or premium gift run.
What This Model Does Better
Nothing to lose in transit
Three captive cables stay with the unit, so the gift still works six months after the event when the loose cable has long gone.
Four charging paths in one SKU
Magnetic pad, plus the three integrated connectors, cover the phones your end users actually carry.
Two output builds, one tooling
Choose the 5W wireless build for volume giveaways or the 22.5W + 15W build for retail-grade runs without changing the mould.
Flat print area on both faces
The 140 x 69mm footprint gives a full-size logo panel on the back and a second panel on the front bezel.
Application Scenarios
- Trade-show and conference giveaways where attendees arrive with mixed phone models

- Retail accessory ranges sold under a distributor's own brand
Who It Is For
- Promotional product distributors sourcing a flagship gift item
- Brand owners building a private-label charging range
- Travel and duty-free buyers who need one SKU to cover all phones

Why Buyers Choose This Model
Cable loss kills repeat impressions
A power bank without its cable is dead weight. Captive cables keep the branded item in daily use, which is the whole point of the spend.
Mixed device fleets
One office has Lightning, USB-C and Micro-USB in the same room. Three built-in connectors plus a magnetic pad cover the room without a bag of adapters.
Thickness versus capacity
At 21mm this is thin enough to pocket while still holding 10000mAh, so it does not end up in a drawer.
Customisation Options
- Housing colour from the standard White, Black and Green, or a Pantone match on request
- Silk-screen or UV print on the back panel and front bezel
- Choice of the 5W or the 22.5W + 15W output build
- Colour paper box, blister card or customised retail packaging
Print method depends on the housing material. We supply a dimensioned print template with artwork approval.
Compared With Other Models
Against FL-FB043, which shares the magnetic pad concept, FL-FB042 trades capacity for thickness: 10000mAh at 21mm instead of 20000mAh at 29mm. Choose FL-FB042 when the unit has to live in a jacket pocket, and FL-FB043 when a two-day runtime matters more than the last 8mm.

- Step 1
Charge the pack fully over the 2.1A/18W input before the first use.
- Step 2
Place the phone centrally on the magnetic face; the magnets set the coil alignment for you.
- Step 3
For the fastest result use one of the built-in cables rather than the wireless pad.
- Step 4
Store at roughly half charge if the unit will sit in a warehouse for more than a few weeks.
