Power Banks and Portable Chargers, Built to Your Specification

Updated 22 Oct 2026 · line pages list every model with its published specification

This line is quoted from a current model list rather than a public spec sheet: cells, capacity and output profile are confirmed per model and hardware revision, and the transport file travels with the shipment. What follows is what a buyer has to pin down before ordering, stated the way we state it in a quotation.

  • Datasheet per model
  • UN38.3 · SDS for air freight
  • Logo and packaging tiers
What this line is for

A power bank is chosen twice: on the shelf, and at the airport

The first choice is commercial — a capacity that justifies a price point, a shell that takes a logo cleanly, packaging that survives a gift box. The second choice is physical: lithium packs move by air against a test summary and a watt-hour figure printed on every unit, and a shipment nobody can fly is a shipment that sits in a warehouse while the campaign date passes.

We quote the line for gift and incentive programmes, mobile-accessory retail, and site or fleet kits where devices have to charge away from a wall. What changes between those buyers is not the channel but the specification: the cell set, the output profile, how much packaging claim your market will let you print, and how the goods are scheduled.

We publish no milliamp-hour or wattage figure on this page. Those numbers come from the model being quoted, measured on production units, and every capacity, cycle or fast-charge claim on your artwork is reviewed against that datasheet before it freezes. If a supplier sends you a capacity figure with no discharge condition attached, you are reading a marketing number, and it will not survive a review by a European buying office or a marketplace compliance team.

Before the proforma

What we confirm, and what we refuse to guess

Rated capacity
Measured at a named discharge current and temperature, in the datasheet for the model being quoted — never a rounded figure lifted from a poster.
Output per port
Protocol support (USB Power Delivery and its profile, plus any private fast-charge mode) is listed per revision, and the adapter bundled in the box belongs to the same scope.
Cell and cycle behaviour
Cell grade, the cycle count at which capacity was re-measured, and the temperature of that test come from our own log, sent with the quotation.
Transport file
UN38.3 test summary and SDS for the pack as shipped, with the watt-hour rating printed on each unit before the goods are booked.
Packaging claims
Every capacity, cycle or charging-speed statement on the carton or listing is checked against the datasheet before artwork freeze; text we cannot evidence is declined, not softened.
Documents for your market
The safety and EMC set applicable to a battery product in the destination market is confirmed per model and hardware revision, including what does not exist yet.
The regulatory part

What a battery order has to answer, stated plainly

Air freight. Lithium packs move against a UN38.3 test summary and an SDS, and cabin rules turn on the watt-hour figure printed on each unit: power banks carried in hand luggage normally sit below 100 Wh per battery, 100 to 160 Wh needs the airline's approval, and above that the goods travel as cargo only. Freight mode is a specification decision, not a shipping afterthought.

Europe. The EU Battery Regulation (EU) 2023/1542 replaces the old directive and adds labelling and capacity-declaration duties in stages, with removability and recycled-content obligations following on a timetable. Importer registrations under WEEE and the national battery regimes — BattG in Germany, the Triman and DEEE scheme in France — sit with the importer, and they carry annual fees and reporting effort that belong in your landed-cost model.

Cell safety and the adapter question. IEC/EN 62133 is the usual cell and pack safety reference for retail sale in Europe; the wider electrical safety and EMC set depends on whether the unit ships with a mains adapter, which changes the scope and the price. We confirm the exact set for the revision quoted rather than a generic certificate claim.

None of the above is a certificate we hold on your behalf. It is the file a battery order needs, and ours is supplied per model and hardware revision, with the transport set attached to the shipment.

Questions power bank buyers ask first

Which figures come with a power bank quotation?
Measured capacity at the stated discharge condition, output per port with the protocol list, charge time to full, the cycle log at named test conditions and the watt-hour rating for transport. Every figure comes from the datasheet for the revision being quoted, not from a rounded marketing number.
Can we order mixed capacities or colours in one shipment?
Yes. Mixed orders across the models in the current list are normal, and the split is confirmed against carton build and production before the proforma invoice, so a first order can cover a price ladder rather than a single SKU.
Can you put our logo and custom packaging on it?
Yes. Logo sits on the standard customisation tiers, custom packaging at its own tier, and a housing change is quoted as ODM with tooling. Send artwork at the sample stage: the finish on a curved shell is a mock-up question, not a PDF question.
Which documents ship with a bulk order?
For a lithium pack the transport set is never optional: UN38.3 test summary and SDS, with the watt-hour rating printed on each unit. The market-facing safety and EMC scope is confirmed per model and hardware revision, and we say plainly which documents do not exist yet rather than implying a scope we cannot evidence.
Is there a wireless or magnetic charging model?
The current model list decides what can be quoted today. Where a wireless version exists we confirm the coil position, the input and output profile, and the case temperature measured on a sample under load, because heat rather than the logo is what decides how a magnetic model reviews.

Sampling and production follow the same policy as the rest of the catalogue: the ladder, the sample stages and the shipping terms are published in the MOQ, sampling and lead times guide, and the charger and battery certification checklist by country covers the document questions in buying-office terms.
