Power Banks

Capacity & Protection — what buyers check (Power Banks)

A power bank is a battery product, so capacity honesty and a real protection board keep it safe — a padded mAh label is the fastest route to a return. The 3.7V rating is not the usable 5V figure, which is lower — quote the usable number or customers feel short-changed. Air freight needs UN38.3 in order, so power-bank cartons should never move without it. Fast charge comes from the controller, not the number of ports, so match the protocol to your market.

Buying on price alone works until the first return, which is why the specification matters more than the headline number.

Specs and checks that matter

• Documentation: Packing list supplied in English and barcoded per SKU
• Cartons: Mixed models and colours consolidate into one shipment
• Quality check: Function-checked before dispatch, category by category
• Defects: Faults are credited or replaced free on your next shipment

Buyer questions

What shipping documents come with it?

UN38.3 test summaries and MSDS are available so your forwarder can move the shipment.

How do I know the mAh is real?

We measure against the factory spec rather than the label and can show the test figures.

Does it support fast charging?

Where the listing names the protocol it is supported; match it to the devices you sell to.

Is there protection circuitry?

Yes — over-charge, over-discharge and short-circuit protection across the range.
