A battery sealer that quits after twenty pouches turns into a returns line, not a product line. A cordless vacuum sealer is a mains-free bag sealer with an internal lithium cell, and the UAH54C pairs 110W, 60kPa suction and a 30cm seal bar with a 2000mAh battery rated for 50-plus sealing cycles per charge. Those four numbers decide whether the unit survives retail, and they also decide your freight paperwork.

What a cordless vacuum sealer is
A cordless vacuum sealer is an external-suction bag sealer that runs from an internal rechargeable cell instead of a wall socket. It draws air out of a pouch through a nozzle, then fuses the open edge with a heated strip. The UAH54C does both at 110W, 60kPa and a 30cm seal width.
What counts as a cordless vacuum sealer?
Two very different products share the cordless vacuum sealer label. The first is a handheld jar or bag pump that only pulls air, with no heat seal at all. The second, which the UAH54C belongs to, is a full-width bench sealer that happens to carry its own battery — the format most buyers mean when they specify a cordless vacuum sealer. Buyers who conflate them end up with a listing that misses returns targets, because the customer expected a seal bar and received a pump.
The distinction matters commercially. A jar pump lands in the $4–$6 band. A cordless vacuum sealer with a 30cm strip is a $10–$20 product, and it competes on cycles per charge rather than on suction alone.
How does 60kPa compare with mains-powered sealers?
Sixty kilopascals is a working figure, not a headline one. Retail listings in this category typically quote 60–90kPa as the working band for household food storage, with entry-level machines around 65–80kPa. Higher is not automatically better: excess pressure crushes bread, pastry and puffed snacks before the seal even forms.
Our own mains-only UAH53T reaches 70kPa at 135W, and the 220W UAHFW15 reaches 80kPa. The UAH54C trades that headroom for portability. For meat, fish, produce and dry goods — the categories most retail listings target — 60kPa removes enough air to hold a pouch flat against the contents.
What does the 30cm sealing width actually cover?
Thirty centimetres spans the width of a standard 28cm freezer pouch with margin at both ends, so the operator seals in one pass rather than repositioning. The heating strip behind it is 3mm. Narrow strips fail more often on moist contents, because any liquid drawn into the seal zone interrupts the weld, which is why the detachable water tray and drainage outlet on this model are functional parts rather than trim.
How many seals does a 2000mAh battery give you?
The UAH54C is rated at more than 50 sealing cycles from a full charge of its 2000mAh lithium cell. That is a working shift for a market stall, a camping trip or a full freezer session at home, and it sits within the range published across the cordless vacuum sealer category, where competing units quote roughly 40 to 110 seals.
Where the 2000mAh figure comes from
Capacity alone does not produce cycles. What matters is how long the pump runs per bag and how much energy the heating strip draws during the weld. The UAH54C moves 3.3 litres per minute, so a typical pouch evacuates in seconds, and the 3mm strip has less thermal mass to bring up to temperature than a 5mm one. Both keep the per-cycle draw low, which is how a 2000mAh cell reaches 50-plus seals.
What drains a charge faster
Three things shorten the count. Wet contents extend pump time because liquid keeps releasing vapour. Thicker or textured bags need a longer weld. And back-to-back cycles leave less recovery time between welds, so the strip starts each seal warmer and the controller compensates. A buyer writing listing copy should quote the rated figure and describe it as dry-goods use, which is how the rating is defined.
Charging a cordless vacuum sealer between shifts
The unit charges over USB, so a retail customer needs no proprietary brick and a distributor ships no region-specific charger. The sealer itself accepts 100–240V, which means one SKU serves every market you sell into and your only plug variable is the cable a customer already owns.
UAH54C specification sheet
The UAH54C is an ABS-bodied external vacuum sealer running 110W at 100–240V, with 60kPa suction, a 3.3 L/min flow rate, a 30cm sealing width over a 3mm heating strip, and a built-in 2000mAh battery. It ships with vacuum bags and an external hose. Catalogue figures below; the approved sample governs a production order.
UAH54C spec sheet
Rev. 2026.09
| Spec | This model | Why it matters |
| Rated power | 110 W | Enough to drive the pump and strip from a battery without a mains cord |
| Voltage | 100–240 V | One SKU covers every export market you sell into |
| Suction | 60 kPa | Inside the 60–90kPa band for household food storage |
| Flow rate | 3.3 L/min ±15% | Short pump time per pouch, which protects the charge count |
| Sealing width | 30 cm | Full-width freezer pouch sealed in a single pass |
| Heating strip | 3 mm | Low thermal mass, so each weld costs less battery energy |
| Battery | 2000 mAh | Rated for 50+ sealing cycles per charge |
| Material | ABS | Standard tooling, low mould cost for private-label colourways |
| Accessories | Vacuum bags, external hose | Jar and container sealing without a separate accessory SKU |
Power, suction and flow rate read together
Wattage on its own tells a buyer very little. Read it alongside flow rate: 110W moving 3.3 L/min describes a pump sized for pouch work, not for a continuous production bench. The 220W UAHFW15 moves 12 L/min, and that is the difference between a household product and a 500-seals-per-day unit.
Heating strip and seal geometry
The 3mm strip is the trade-off that makes a cordless vacuum sealer viable at this price. Wider strips lay down a more forgiving weld on moist or thick film, which is why our corded UAH53T runs a 5mm strip. On a battery unit, every millimetre of strip is energy the cell has to supply, so 3mm plus a drainage path is the design that keeps the cycle count where it is.
Water tray, drainage and the sliding cutter
The detachable water tray catches liquid pulled from marinades and thawing produce before it reaches the seal zone, and the drainage outlet empties it without dismantling the unit. The built-in sliding cutter lets the operator cut bag stock to length from a roll, which removes a second accessory from the retail box.
On a corded sealer you design for the weld. On a battery sealer you design for the charge, and every millimetre of heating strip you add is a seal the customer no longer gets.

How the UAH54C compares with our other sealers
Against our own range, the UAH54C is the low-cost cordless vacuum sealer: same 30cm seal and 2000mAh cell as the pricier models, at the lowest tier price of the battery group. The trade is suction and features, not seal width. Corded siblings buy you pressure and duty cycle instead of portability.
| Model | Power | Suction | Seal width | Battery | Lowest listed tier |
|---|---|---|---|---|---|
| UAH54C Cordless value | 110 W | 60 kPa | 30 cm | 2000 mAh | $10.80 @ 5,000 |
| UAHTG4 | 50 W | 75 kPa | 30 cm | 2000 mAh | $13.40 @ 4,999 |
| UAH72C | 110 W | 60 kPa | 30 cm | 2000 mAh × 2 | $19.00 @ 3,000 |
| UAH53T | 135 W | 70 kPa | 32 cm | Mains only | $9.86 @ 5,000 |
| UAHFW15 | 220 W | 80 kPa | 29 cm | Mains only | $56.00 @ 500 |
Against the 50W UAHTG4
The UAHTG4 is the feature-rich cordless vacuum sealer in our range: 75kPa, a 4 L/min pump, temperature control with Temp+ and Temp− steps, six operating modes and a waterproof touch screen. It costs more per unit at every tier. Choose it when your listing sells on modes and control. Choose the UAH54C when the listing sells on price and the customer wants one button.
Against the mains-only UAH53T
The UAH53T undercuts the UAH54C on price and beats it on specification — 135W, 70kPa, a 32cm seal, a 5mm strip and support for 1,000 continuous vacuums in one go. It has no battery. That single difference splits the market cleanly: kitchen-counter buyers take the corded unit, and anyone sealing away from a socket needs a cordless vacuum sealer.
When the 220W UAHFW15 is the right call
The UAHFW15 sits in a different bracket at $56.00 per unit. Its 220W motor, 12 L/min flow, 80kPa suction, five-layered strip and filtered liquid extraction container are rated for 24-hour continuous use at up to 500 seals a day. That is a light-commercial specification. It is the wrong answer for a battery-led retail programme and the right one for a butchery or a meal-prep operation.
Does the built-in battery change your shipping paperwork?
Yes. The lithium cell built into a cordless vacuum sealer moves the shipment into dangerous-goods handling under UN 3481, and carriers require a UN 38.3 test report before they accept the booking. Nothing about the product changes. What changes is the documentation set that has to travel with the carton.
UN 3481 and the UN 38.3 test report
UN 38.3 is the United Nations transport test protocol for lithium cells: altitude simulation, thermal cycling, vibration, mechanical shock, external short circuit, impact or crush, overcharge and forced discharge. A cell installed in equipment can be tested without disassembly. Carriers and port authorities ask for the report together with a safety data sheet, and IATA publishes the current air-transport requirements for exactly this class of shipment.
Air freight versus sea freight
Air is the stricter of the two. State of charge is capped, packaging marks are prescribed, and a mis-declared consignment is refused at acceptance rather than at destination. Sea freight is more forgiving on state of charge but still requires the same test report at booking. For a first cordless vacuum sealer order, sea freight on FOB terms keeps the documentation simple and the cost predictable.
What we supply with the order
We issue the UN 38.3 report and the safety data sheet for the cell used in the UAH54C, along with the commercial invoice and packing list, so your forwarder has a complete file at booking. Certification beyond that — CE, RoHS, FDA food-contact documentation for the bag stock — depends on your destination market, and we supply what applies to your order. The FDA maintains the food-contact substance framework that governs the bag side of the programme in the United States.
Who should stock this cordless vacuum sealer?
The UAH54C suits buyers selling portability at a mass-market price: general merchandise retail, marketplace sellers, outdoor and camping channels, and private-label programmes that want a cordless vacuum sealer without a battery premium. It is not a light-commercial unit and should not be positioned as one.
Retail and e-commerce buyers
At $10.80 per unit in the 5,000-piece tier, the model leaves room for a competitive shelf price and a normal retail margin while still reading as a premium feature set on the listing: a cordless vacuum sealer with a 30cm seal, a cutter and a water tray. The one-button operation reduces support contacts, which is what protects the margin after the sale.
Outdoor, camping and market-stall channels
This is where the battery earns its cost. Anglers portioning a catch, hunters at a camp, growers at a farmers’ market and caterers loading a van all seal away from a socket, and a cordless vacuum sealer is the only format that serves them. Fifty-plus cycles covers a day’s work in each of those settings, and the USB charge cable means a power bank or a vehicle socket is enough to reset it.
Private-label programmes
A private-label cordless vacuum sealer starts from the same tool: the ABS body takes custom colourways with standard tooling, and logo, packaging, manual and accessory bundle are all specifiable. We manufacture our own range and also trade a wider household and kitchen catalogue, so a private-label programme can draw a matched set of products from one supplier and one shipment.
How we manufacture the UAH54C
Every cordless vacuum sealer we ship is built on our own lines in Guilin, China, where we have manufactured household appliances since 2005, across four controlled stages: tooling and moulding, pump and PCBA burn-in, seal-integrity and vacuum testing, then compliance and warranty release. Seven assembly lines run inside a 15,000 m² facility, and every unit leaves with a 12-month warranty.
In-house tooling and moulding
The ABS housing, water tray and cutter carriage come off our own moulds. Owning the tool is what makes a private-label colourway a scheduling question rather than a new development project, and it keeps the tray-to-body fit consistent between production runs.
Pump and PCBA burn-in
Pump assemblies and control boards are powered up and run before they meet the housing. On a cordless vacuum sealer this stage also covers the charge and discharge path, because a cell that behaves differently under load is the fault that surfaces later as a short cycle count in the field.
Seal-integrity and vacuum testing
Assembled units are run against a pouch to test that the pump reaches its rated pressure and that the 3mm strip lays a continuous weld across the full 30cm. Quality control looks for the two defects that generate returns: a weld gap at the edge of the strip, and vacuum loss after the lid releases.
Compliance and warranty release
Units are built to the certification scheme your market requires — CE and RoHS for European export, with the UN 38.3 report covering the cell in transit. We name only the marks we hold and issue the documents relevant to your order. Every unit ships with a 12-month warranty against manufacturing defects.
Pricing, order quantities and carton logistics
The UAH54C cordless vacuum sealer price ladder starts at $12.50 per unit for 500 pieces and falls to $10.80 at 5,000, quoted FOB China. Fifteen units pack per export carton at 17.5 kg gross. Payment is 30% deposit with the balance before shipment, and lead time runs 15–30 days after deposit.
Quantity tiers
| Order quantity | Price per unit | Saving vs 500-piece tier |
|---|---|---|
| 500 units | $12.50 | — |
| 1,000 units | $11.50 | $1.00 |
| 5,000 units | $10.80 | $1.70 |
Smaller trial orders are available on request ahead of a first production run, and samples ship in 3–7 days.
Carton and cube arithmetic
The retail box measures 44 × 12 × 8 cm and the unit itself 38.8 × 8.68 × 7.3 cm at 0.86 kg. Fifteen retail boxes go into an export carton of 45.5 × 41.5 × 38 cm weighing 17.5 kg gross — 0.0718 m³ per carton, or roughly 0.0048 m³ of cube per unit. Multiply that by your order quantity before you compare landed cost against a bulkier competing model, because on a low-value appliance freight cube moves the landed price more than the unit price does.
Payment terms and Incoterms
Standard terms are 30% deposit by T/T with the 70% balance settled before shipment, and Alibaba Trade Assurance is supported. We quote FOB China as the default, with EXW and CIF available where your freight arrangement calls for it. Lead time is 15–30 days for bulk production after the deposit clears.
How much shelf life does vacuum sealing actually add?
Removing air slows oxidation and freezer burn, which is why vacuum-sealed meat is commonly quoted at two to three years frozen against six to twelve months for conventional packaging. The USDA Food Safety and Inspection Service treats freezer times as quality windows rather than safety cut-offs.
Why the freezer number moves so much
Food held continuously at 0°F (−18°C) stays safe indefinitely; what degrades is texture, colour and flavour. Air trapped against the surface is what drives that degradation, so pulling the pouch flat against the contents at 60kPa is the mechanism behind the longer quality window. This is the claim your listing copy can make honestly.
What a wider seal buys on moist foods
Seal failure, not suction, is the usual cause of a spoiled pouch. Narrow welds are more likely to open when frozen contents shift or when residual moisture sits in the seal zone. On the UAH54C the 3mm strip is paired with the water tray and drainage outlet for that reason: keep liquid out of the weld and the narrow strip performs.
Which categories sell the accessory attachment
The external hose turns the unit into a jar and container sealer, which opens dry goods, coffee, rice and sous-vide prep as listing categories without adding a second product. Retailers who merchandise the hose alongside the sealer report it as an attachment sale rather than a feature bullet.

Conclusion
The UAH54C is a cordless vacuum sealer built to a retail price rather than a specification sheet: 110W, 60kPa, a 30cm seal and 50-plus cycles from a 2000mAh cell, from $10.80 per unit at 5,000 pieces. Budget for the lithium documentation and the freight cube, and the rest of the programme is straightforward.
If the buying decision turns on modes and control, the UAHTG4 is the better cordless. If it turns on pressure and duty cycle, the corded UAH53T or UAHFW15 answer that. If it turns on selling portability at a mass-market price, this is the cordless vacuum sealer in our range that does it most cheaply.
