Model by model
NHK-TU10U1A1C (10W) — the bundle basic: A+C outputs at 5V, CCC listed, foldable US plug. It exists for boxes that must include a charger and nothing more. NHK-TU15U1A1C (15W) — adds 9V and 12V steps on the C port for older fast-charge phones, CCC listed. NHK-X18WU1A (18W) — the certification outlier: UL, CB, FCC, CE and PSE on one value model, which makes it the default pick when a price-led program still has to pass a retailer's compliance review. NHK-X20WU1A1C (20W) — the standard phone PD profile at 20W with CB, FCC, CE, PSE and RoHS listed. NHK-C30U1C (30W) — the line's ceiling: full 20V/1.5A PD with PPS 3.3-11V/3A, CE and RoHS listed; it overlaps the bottom of the GaN 30W tier, and the choice between them is housing and price.
When to buy this line instead of GaN
When the program is judged on unit price at phone wattages and the buyer's compliance list is covered by the listings above. When the program needs laptop wattage, multi-port splits or PPS above 11V, the correct catalogue is the GaN line — do not stretch a value model into a laptop claim. The protocols behind these tiers are explained in PD vs QC fast charging.
Mixed-line programs
Most buyers do not choose between this line and the GaN line; they allocate. A common structure: this value line carries the bundle and promotional SKUs, while two or three GaN tiers carry the margin. The lines share plugs, terms and the same sample discipline, and the 30W NHK-C30U1C deliberately overlaps the bottom of the GaN ladder so a program can graduate customers upward without changing supplier. When you request the quote, ask for both lines in one document - the per-item MOQ applies per model, and seeing the full ladder priced at once prevents the tier gaps that strand volume later.
Certification planning belongs in the same conversation: if your market list includes Japan, the NHK-X18WU1A's published PSE listing makes it the structural choice of this line regardless of its mid-pack wattage - an example of listings, not watts, deciding a SKU.
