Verify My Supplier Sample

Supplier Claims Can Change Once the Product Is Opened

A supplier advertised a portable tire inflator with a 5,200mAh battery pack.

Supplier Claim

Two 2,600mAh cells provide a total capacity of 5,200mAh.

Measured Finding

The two cells were connected in series. Series wiring increases voltage, but the rated pack capacity remains 2,600mAh.

Buyer Risk

The incorrect capacity claim may create unrealistic runtime expectations, inaccurate product listings and avoidable customer complaints.

Procurement Action

Define the cell model, pack voltage, rated capacity and verification method in the purchase specification before approving the order.

Results apply only to the inspected sample and test scope described in the report.

SUPPLIER SAMPLE RISK CHECK — FROM US$299

Start With a Supplier Sample Risk Check

Designed for buyers who already have a supplier quotation, product link or physical sample but need an independent review before placing an order.
