About Our Editorial Team
Every guide and product description on this site goes through our internal review before publication. We are a small wholesale operation, not a content farm, so the same people who handle parts also write about them.
Who writes here
Our editorial work is a collective effort by the staff of Special Electronics Co., Ltd — the company that operates Laptop Power Jack Inc. Most articles are drafted by our technical team based on specifications we actually source, repairs we have observed in 12 years of laptop parts wholesale, and questions our customers ask repeatedly through mail@laptoppowerjackinc.com.
We do not publish under invented personal bylines. When a guide cites a specific repair procedure, that procedure has been performed in our warehouse. When a guide states a wattage or pin count, we have measured it on the part we sell.
How we source facts
- Original equipment specifications from manufacturers (HP, Dell, Toshiba, Acer, Lenovo, Samsung, Apple) where the part is a genuine OEM unit.
- Compatibility tests done in our shop on a working laptop of the listed model before we publish a part as compatible.
- Customer feedback from 14-day return cycles. If a part is returned more than twice for the same defect, we re-check the listing and update or pull it.
- Standards documents for connector dimensions and electrical ratings (IEC, USB-IF, IEEE) when general claims are made.
Our update policy
Pricing changes when wholesale costs change — typically every 4-6 weeks. Specifications and compatibility lists are updated when we onboard a new SKU or stop carrying one. Repair guides receive a review at least once a year; if a procedure becomes outdated because of a new revision of a laptop board, the guide is rewritten or removed rather than left stale.
We mark each article with a publication date and refresh it when the underlying facts change.
Corrections and feedback
If you spot a factual error — wrong wattage, wrong pin spacing, broken procedure step — email mail@laptoppowerjackinc.com with the URL and the correction. We respond within 24 business hours and credit the source if you want public attribution.
We do not run sponsored posts. Affiliate revenue from external retailers is disclosed at the bottom of any guide where it applies; most guides earn nothing because they explain a procedure rather than recommend a specific seller.
