<h2>Wholesale and OEM/ODM</h2>

<p>We support wholesale orders, samples and OEM/ODM branding or packaging. Share your quantity, destination country, required AC voltage and customization needs to receive a tailored quotation.</p>

<h2>FAQ</h2>

<h3>How long is the lead time?</h3>

<p>Typical lead time is about 7–15 days, subject to quantity, customization and production schedule.</p>

<h3>Can I order a sample?</h3>

<p>Yes. Contact us with the destination market and shipping requirements so we can confirm sample availability.</p>

<h3>Can you provide battery shipping documents?</h3>

<p>We can confirm available shipping methods and the required battery documents for the destination before quotation and shipment.</p>

<h2>Port and charging information transcribed from the original product graphics</h2>
<p>The KK7009 images contain useful connection information that should not be left only inside a picture. The text below is a readable transcription of the original graphics; confirm the final port layout and supplied accessories for the production batch before ordering.</p>

<h3>Charging methods shown in the graphics</h3>
<ul>
<li>The product graphic headline states "3 ways to recharge". It labels indoor charger charging and outdoor solar panel charging, while the product face also shows separate DC IN and SOLAR input labels.</li>
<li>The published product specification lists an 18V / 100W solar input and AC charging. Ask us to confirm the exact AC adapter, DC input cable and solar-panel accessory included with the selected version.</li>
<li>For solar charging, use a compatible 18V panel and check polarity before connection. Do not connect a high-voltage PV string directly to this portable power station.</li>
</ul>

<h3>Ten-port layout shown in the original front-panel graphic</h3>
<p>The graphic describes ten-port simultaneous use, three types of output, two charging modes and a total AC output power of 300W. The labels are:</p>
<ul>
<li>USB: three USB outputs, marked USB 5V, with a USB turn key.</li>
<li>AC: two AC output sockets with an AC turn key. The page specification identifies the AC version as 110V or 220V.</li>
<li>DC: four DC outputs marked DC 12V with a DC turn key.</li>
<li>Controls and display: boot key, AC turn key, function display and indicator buttons for LED and AC operation.</li>
<li>Charging panel: adaptive charging, DC IN and solar charging labels.</li>
</ul>
<p>"Use simultaneously" describes the port layout shown in the marketing graphic, not an instruction to exceed the 300W rated output. Check the combined AC, DC and USB demand, startup surge and the limit of each individual port before connecting multiple devices.</p>

<h3>Housing and battery input labels shown on the product images</h3>
<p>The front and side images show an LCD function display, LED light panel, carry handle and ventilation openings. The rear label identifies the unit as an outdoor power supply and shows DC12–15V battery input with positive and negative terminals. The label also visibly carries RoHS, ISO and CE marks; the applicable declaration and test documents should be confirmed for the destination market rather than inferred from the image alone.</p>

<h2>How to choose the 300W 307Wh station for a real use case</h2>
<table>
<thead><tr><th>Your daily need</th><th>What to check before ordering</th><th>Why it matters</th></tr></thead>
<tbody>
<tr><td>Phone, camera, router or lights</td><td>USB 5V/3A, DC 12V/3A and the expected hours of use</td><td>These loads normally use the DC/USB paths more efficiently than an AC adapter.</td></tr>
<tr><td>Camping or RV appliances</td><td>AC voltage version, device rated watts and startup surge</td><td>The unit is rated 300W and uses a modified-sine-wave inverter; motors, compressors and sensitive equipment need confirmation.</td></tr>
<tr><td>School or emergency backup</td><td>Required runtime, recharge window, number of devices and battery shipping documents</td><td>307Wh is the stored energy reference; runtime changes with conversion losses and the actual load.</td></tr>
<tr><td>Outdoor solar replenishment</td><td>18V panel compatibility, 100W solar-input limit, connector polarity and sunlight conditions</td><td>A panel with the wrong voltage can stop charging or damage the input.</td></tr>
</tbody>
</table>

<h3>Runtime estimate customers can understand</h3>
<p>Start with the 307Wh energy capacity, then divide by the actual continuous load and allow for inverter and cable losses. For example, a 30W DC/USB load will not run for exactly 10.2 hours because conversion efficiency, battery reserve and temperature affect the result. Send the device wattage and desired runtime for a more useful recommendation.</p>

<h3>Common daily problems and answers</h3>
<table>
<thead><tr><th>Problem</th><th>Practical checks</th></tr></thead>
<tbody>
<tr><td>AC output does not work</td><td>Press the AC turn key, check the AC voltage version, remove overload devices and test with a small known-good load. A modified sine wave output may not suit every motor or sensitive charger.</td></tr>
<tr><td>USB or DC output is off</td><td>Press the USB/DC turn key, confirm the device cable and check whether the protection circuit has switched the output off because of overload or short circuit.</td></tr>
<tr><td>Solar charging is slow or zero</td><td>Check that the panel is compatible with the 18V input, measure panel voltage in sunlight, confirm polarity and remove shading. Do not use a series PV string that exceeds the input limit.</td></tr>
<tr><td>The display turns off quickly</td><td>Check the battery state, wake the unit with the boot key and confirm whether the display has an automatic timeout. A photo of the display and load helps us diagnose the state.</td></tr>
<tr><td>The station cannot start a fridge, pump or power tool</td><td>Compare the appliance startup surge with the station's available surge specification. If the surge value is not published for the batch, ask us before placing the order.</td></tr>
<tr><td>Battery gets hot or smells unusual</td><td>Stop charging/discharging, disconnect external input and contact the supplier. Do not open the housing or continue testing a swollen or damaged battery.</td></tr>

<h2>Send these details for a fast wholesale quotation</h2>
<p>Tell us the required AC voltage (110V or 220V), target quantity, destination country, devices to be powered, continuous and startup watts, expected runtime, preferred solar-panel input, logo/color/packaging requirements and whether battery transport documents are needed. We can then confirm the workable KK7009 configuration, accessory list and shipping method instead of quoting only a nominal 300W number.</p>
