Perfekt — här kommer din SEO-optimerade brittiska engelska version av koden.

<h2 style="text-align: left;"><strong>Experience warmth &amp; comfort – wherever you sit</strong></h2>
<p style="text-align: left;">Dynan is a rechargeable heated seat cushion that keeps you warm on the patio, in the boat or at the stadium – completely cordless and hassle-free. With the included power bank and three heat settings, you get fast, even warmth directly close to your body.</p>
<p style="text-align: left;">Lightweight, portable and energy-efficient – designed for the Nordic climate.</p>

<h2 style="text-align: left;">Benefits of Dynan:</h2>
<ol>
<li><strong>Power bank included:</strong> 20,000 mAh for up to 15 hours of heat per charge (depending on setting and outdoor temperature).</li>
<li><strong>Three heat levels:</strong> easily switch temperature with the button on the cushion.</li>
<li><strong>Portable design:</strong> discreet inner pocket for the power bank, charges via USB-C.</li>
<li><strong>Perfect size:</strong> 40 × 40 cm – fits most chairs, benches and storage boxes.</li>
<li><strong>Durable everyday design:</strong> water-repellent canvas that’s easy to wipe clean.</li>
</ol>

<h2 style="text-align: left;">How it works</h2>
<p style="text-align: left;">Place the included power bank in the inner pocket, connect the cable and hold the power button to start. Press to change heat level. Hold again to turn off. Everything is built to be simple, fast and robust – no wall sockets, no cords, just pure freedom.</p>

<h2 style="text-align: left;">Heated seat cushion – more efficient than an electric blanket</h2>
<p style="text-align: left;">A heated seat cushion focuses the warmth where it’s most effective – in the seat. It reduces wasted heat and often feels warmer outdoors than infrared heaters. Dynan is easy to bring to the stands, the boat or the patio. If you want something to wrap around your body indoors, an electric blanket is ideal, but for outdoor comfort, a heated seat pad wins on portability and energy efficiency.</p>
