A4 Zipper Portfolio with Power Bank Charging
An A4 zippered portfolio with a power bank built into the interior, charged through an exposed USB port. The zip closes the whole folder, so the battery, cables and documents travel together, and a phone can be charged from inside the folder while it is closed and in a bag.

What this one is
Zippered portfolio with built-in power bank
The power bank is held in a dedicated interior pocket with the charging port exposed through the lining, so the folder can stay zipped while a phone charges. Unlike a wireless charging portfolio, this version uses a cable, which means it works with any device rather than only those with a wireless coil. The rest of the interior carries the standard A4 folio layout. Battery capacity and output current are quoted against the devices to be charged, and the pocket is sized so the battery can be removed for inspection.
- Internal power bank — Held in a dedicated pocket with the port exposed through the lining.
- Cable charging — Works with any device rather than only wireless-charging phones.
- Closes while charging — The folder can stay zipped with a phone charging inside.
- Removable battery — Pocket sized so the cell can be taken out for inspection or replacement.
Where it gets used
Who specifies a built-in power bank
Sales organisations give these to field teams who travel between sites without reliable power. Exhibition and events companies issue them to staff working a stand for a full day. Trade and logistics companies use them for staff on the road. The cable-based version is chosen over wireless where the workforce uses a mix of devices, since a cable works with all of them.
What we can change for you
Made to your drawing, not to our catalogue
This item is not picked off a shelf. Every part of it is specified before it is made, and these are the parts buyers change most often on a portfolios & document cases programme. Send whatever you have — a drawing, a photo of a sample you like, or a rough sketch — and we quote against it.
- Outer size and orientation — A4, A5, Letter or Legal, portrait or landscape, or a size cut to your drawing.
- Cover material and caliper — PU leather, bonded leather or linen, with the board caliper you specify.
- Charging module — Wireless charging pad or an integrated power bank, with the output and connector you specify.
- Interior layout — Device pocket, cable channel, notepad, card slots and a pen loop arranged around the module.
- Branding — Foil stamping, blind debossing, screen print or an indicator window with your mark.
- Packing and compliance — Retail box with the battery documentation your market requires, plus the markings for shipping.
Anything not on this list is a question rather than a no. We work from your artwork or a rough sketch, and cutting dies and covers are engineered in-house — so a change costs you a conversation, not a new supplier.
How your order is made
Tooling, printing and binding on our own line
Covers are cut and wrapped in our own workshop, and the zips, magnets or ring mechanisms are fitted on the same line. That is why the sampling date we give you is one we can hold.
- Tooling and dies — cutting dies and covers are engineered in-house, so a change to the shape is a conversation rather than a new supplier.
- Printing and finishing — offset and screen printing, foil stamping, blind debossing, spot UV and edge painting all run on site.
- In-line QC — checks at cutting, stitching and packing, not only at the end. You get the inspection photos before the cartons close.
- Export and documentation — cartons, pallets, labelling and shipping documents prepared to your forwarder specification. 94.8% of what we make is exported.

How to order
From spec to shipment in four steps
Most buyers have a sketch, a sample, or a brief. We turn it into a confirmed sample and then into a repeatable production run.
Product type, dimensions, quantity, logo, and deadline — even a photo is enough.
Unit price, tooling, sample cost, and lead time — usually within one working day.
We make a physical sample for your review before anything goes to bulk.
In-line QC, pre-shipment photos, then packed and shipped to your forwarder.

Working with us
Files, tooling and terms
The same terms apply to this item and to the rest of your order, so the budget and the schedule can be planned before anything is committed.
- Artwork — Vector files (AI, EPS, PDF or CDR) are what embossing, foil and screen print need. A photo, a sketch or a physical sample is enough to start — we tell you before anything is charged if a file has to be rebuilt.
- Tooling — Charged only when the item needs a new mould, die or deboss plate. It is quoted separately and stated upfront — never added later.
- Samples — A stock sample is free (you cover the courier). A customised sample is chargeable and the cost is credited against the production order once it is confirmed.
- Payment — Invoiced in US dollars from our company account. Standard terms are T/T — 30% deposit, 70% before shipment — or an L/C at sight for container orders.
- Shipping — FOB Ningbo or Shanghai, CIF, and DDP to Europe and North America. DDP includes duties and final-mile delivery.
- Mixed containers — Several categories can ship in one container, which is how buyers keep the quantity per item down while still filling a shipment.
- Confidentiality — We sign an NDA before you send drawings.
- Documents — One inspection report and one set of documents cover the whole order, whatever the mix of items.
Buyer questions
Does it charge while zipped?
Yes. The port is exposed through the lining so a phone can charge with the folder closed.
Which devices can it charge?
Any device with a matching cable, unlike a wireless version which only works with compatible phones.
Is the battery removable?
Yes. The pocket is sized so the cell can be taken out for inspection or replacement.
Can you work from a sample or a photo instead of a drawing?
Yes. A photo of a competitor’s sample, a physical sample or a rough sketch is enough to start. We return a written specification for approval before any tooling is cut.
Which logo methods can be used on the cover?
Foil stamping, blind debossing, screen print, spot UV or a metal badge. On PU we adjust the debossing depth to the sheet thickness so the impression stays sharp and does not crack along the fold.
Can we test the charging module before the full run?
Yes. The sample is made with the production module, not a placeholder, so the fit and the output are both verified before tooling is committed.
How is the power module handled for shipping?
A portfolio with a battery is not the same shipment as a portfolio without one. Tell us the destination market and we will confirm the documentation and the markings the battery needs before we quote.
Will a reorder match the first run?
We hold the approved specification on file — material, caliper, lining, foil colour, stitch and packing — and manufacture repeat orders against it instead of starting over.
What is the minimum order quantity?
Minimums are set per item and depend on material, tooling and finish. This item starts from 300 pcs; the exact minimum is confirmed with your quote.
How do you stop the cover from cracking at the spine?
Board caliper and hinge allowance are specified together, not separately. On padded covers we add a hinge allowance at the fold, which is where most portfolios fail first.
