Compact pump-system approval
The six compact catalog records are pump-style sourcing routes, not complete sealed systems by themselves. Approve the intended valve, bag or container interface, nozzle and accessories, charging set and operating result with the current sample.
Wholesale only; MOQ starts from 1000 PCS. OEM files and private quotation follow the approved compact model, storage interface, charging set, included parts, quantity and destination version.
Buyer decision points
A compact pump cannot be approved from its shell image or charging field alone. The purchase order must identify the complete storage system and the exact items included in the retail box.
For importers, food-storage distributors and private-label buyers that can identify the intended valve, bag or container system, approve a current sample and own local product, channel and market-entry decisions. Retail and one-piece requests are excluded.
State the storage item, valve construction, opening dimensions and any nozzle or adapter before choosing K01, K02, K04, K05, K15 or K15B. Catalog appearance does not prove universal interface compatibility.
Approve connector, rated input, cable, battery information where applicable, nozzle, adapter and every included item on the current sample. Source-sheet wording is a lead for verification, not a finished rating-label approval.
Use the intended storage item to agree the operating sequence, interface fit, evacuation observation, repeat-cycle check and acceptance record. Any preservation or performance claim must stay within evidence for that tested order version.
Complete-system approval
The tested sale unit includes more than the pump body. Approve the storage interface, charging set, included parts, instructions and packing as one named order version.
Provide the intended bag or container, valve type, opening dimensions, material and buyer-owned reference. If the buyer expects several storage items, list and test each one separately.
Record the pump outlet, nozzle or adapter, seating method and fit with the intended valve. A visual resemblance between models cannot establish interchangeability.
Confirm the current sample connector, rated input, cable and battery information where applicable. Tie the rating label, manual and pack contents to the same approved device version.
Agree how the device is positioned, started and removed, what observation records evacuation and how repeat cycles are checked. The procedure should use the buyer's intended storage item.
List the pump, nozzle or adapter, cable, storage accessories if any, manual and every item promised on the color box. Inspection should verify the same set.
Keep preservation, compatibility, battery and performance wording inside available evidence. The buyer defines local warranty and consumable supply; Yaoyuan coordinates the approved factory-side files and inspection inputs.
Catalog-family review
The six compact records form three practical comparison groups. Their published fields help narrow the sample list, while interface fit, actual charging identity, operation and packing remain open controls.
Both source records list 4-5.2V and 400mAh fields with PP+ABS construction. Published body dimensions differ. Confirm the current labels, connector, complete set and intended interface on separate samples.
Both records list 5V/5W and PP fields with a 59 x 59 x 142 mm color-box field. Their published body heights differ. Do not reuse one model's artwork, interface or pack-content assumptions for the other.
The source records list different 5V power fields, body heights and matching 120 x 95 x 60 mm color-box fields. Verify the actual samples and charging sets before deciding whether they belong in one range.
Six source-linked sample routes
Each link preserves the source image and published catalog fields for that route. The current sample review must close interface, charging identity, included parts, operation and packing.
Published source fields: Charging voltage: 4-5.2v; Product size: 51mm*99mm; Carton: 600*310*255mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
Published source fields: Charging voltage: 4-5.2v; Product size: dia. 51mm*109mm; Carton: 600*310*255mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
Published source fields: Charging voltage: 5V/5W; Product size: dia. 51mm*84mm; Color box: 59*59*142mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
Published source fields: Charging voltage: 5V/5W; Product size: dia. 51mm*94mm; Color box: 59*59*142mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
Published source fields: Charging voltage: 5V/25W; Product size: dia. 63mm*114mm; Color box: 120*95*60mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
Published source fields: Charging voltage: 5V/7W; Product size: dia. 63mm*106mm; Color box: 120*95*60mm. Confirm the current sample, storage interface, charging set, included parts and packed version before approval.
System-specific inquiry
The catalog records identify physical models and selected source fields, but they do not prove universal compatibility with every valve, bag or container. The buyer should identify the intended storage system and approve the exact interface, nozzle or adapter, operating sequence and result on the current sample.
Charging identity must be confirmed on the actual order version. Record connector, input, cable, battery information where applicable, included accessories and manual instructions. A portable-device quotation is incomplete when the compatible storage item and pack contents are still undefined.
