About
A factory, not a trading desk
OLIFI manufactures UPS systems in Shenzhen, China — SMT, assembly, aging burn-in and final QC all under one roof. We built our name on one promise: what we ship is what we tested.
Why buyers work with us directly
When you buy from a trader, there are two companies between you and the people who actually build your product. When you buy from OLIFI, you get factory pricing, factory QC and factory answers — plus the ability to put your own brand on it.
We started in 2009 as a power-electronics workshop and grew into a full manufacturer with automated SMT lines and a dedicated burn-in room. Today we ship to more than 60 countries under our own and our customers' brands.
Manufacturer first
We own our SMT lines, assembly and burn-in rooms. No trading company in the middle — you talk to the people who build the product.

Every unit runs full-load aging and a 40-point QC before shipping. Our factory floor is our quality statement.
