<p>All USB-C ports on Omnicharge products support USB Power Delivery. USB Power Delivery (or PD, for short) is a unified charging standard that can be used all across USB-C devices.&#xA0;Normally, each device is charged with its own adapter, but with USB-PD, one universal USB-C adapter will be able to power a wide variety of different devices including laptops, tablets, phones and more. USB PD uses voltage profiles that are standardized across PD compatible devices.</p>
<p>Not all USB-C devices use USB PD, but this is mostly a problem with older USB-C devices. Most modern USB-C devices are compatible with USB PD.</p>
<p>&#xA0;</p>

What is USB PD?

<div>This question is rather complicated since your laptop&apos;s power consumption fluctuates a lot depending on if you&apos;re gaming or simply browsing the Internet on the laptop. This affects the time and percentage Omnicharge can charge your laptop. Remember, this is a small pocket-sized power bank, and laptop charging expectations should be set accordingly, as laptop batteries will often be significantly larger. The Mobile 12,800 is primarily designed to be a portable power bank, which has the ability to charge laptops. While laptop charging is not the primary function of the battery, it is great for topping up the laptop battery.</div>
<div>&#xA0;</div>
<div>So to simplify the question,&#xA0;we use a more objective method by comparing Omnicharge&apos;s battery capacity to the laptop&apos;s internal battery capacity. Also considering the efficiency loss of Omnicharge&apos;s conversion circuits,&#xA0;the equation of charge percentage is:</div>
<div>
<div class="wysiwyg-text-align-left wysiwyg-indent1">&#xA0;</div>
<div class="wysiwyg-text-align-left wysiwyg-indent2"><strong>Omnicharge&apos;s battery capacity / laptop&apos;s internal battery capacity * Omnicharge&apos;s conversion circuits efficiency</strong></div>
<div class="wysiwyg-text-align-left wysiwyg-indent1">&#xA0;</div>
<div>Take the Omni Mobile 12,800 and the 13&apos;&apos; MacBook air (2019 model), the Mobile 12,800 has a 46Wh capacity and the 13&apos;&apos; MacBook Air has a 49.9Wh internal battery; the Omnicharges conversion efficiency is around 90%. Put these numbers in the above equation and we get:</div>
<div>&#xA0;</div>
<div class="wysiwyg-indent2"><strong>46Wh / 49.9Wh *&#xA0;<span class="il">90</span>% =&#xA0;0.83</strong></div>
<div class="wysiwyg-indent1">&#xA0;</div>
<div>This means that the Omnicharge can charge the 13&apos;&apos; MacBook Air around 83%. This is assuming that the laptop is turned off or in sleep mode. Operating the laptop while charging will impact this calculation.</div>
<div>&#xA0;</div>
<div>Remember that you might get significantly different results in real life. Let&apos;s say that your laptop battery is already fully charged, and you are only using the Omnicharge to extend the battery life. Since the laptop battery is already full, the power draw will be significantly lower, which also means that the Omnicharge will output less heat, and will, therefore, have higher efficiency.&#xA0;</div>
</div>

<p>USB-C on the mobile 12,800 is primarily plug and play. Just make sure that the Omnicharge is switched on before connecting the USB-C cable. First, connect the USB-C cable to the Omnicharge, before plugging it into your device. If the device does not start charging within 10 seconds, pull the USB-C cable in and out of your device. If you are still having trouble, try using a different cable.</p>
<p><em>Note: On PixelBooks and Chromebooks, you will receive a prompt at the bottom right of your screen, asking if you want to charge from this source. The laptop will not start charging until you accept this prompt.</em></p>

<p><span class="wysiwyg-font-size-x-large" style="font-size: 24px;">Charging from the USB-C port</span></p>
<p><span class="wysiwyg-font-size-medium" style="font-size: 16px;">Recharging the Omnicharge from the USB-C port is also plug and play. If you plug in a regular USB-C charger, the Omnicharge should detect this as a power source, and accept the power input. In some cases, if you want to recharge the Omnicharge from for example your laptop, the Omnicharge might have trouble negotiating which direction the power should go. In this case, first turn off your Omnicharge, before connecting the cable. If you wish to utilize pass-through charging, wait 15 seconds before turning the Omnicharge back on.</span></p>

Using the USB-C port

The first step in all troubleshooting on Omnicharge products is to attempt a full calibration of the unit. This is done by first depleting the battery until it shuts itself off, followed by an overnight charge. If you are having trouble recharging yo

<p><span class="wysiwyg-font-size-medium" style="font-size: 16px;">If you are having trouble recharging your Omnicharge, first try to use a different charging cable and a different AC adapter. You can try using the charger from for example a phone or tablet to recharge the Omnicharge.&#xA0;</span></p>
<p><span class="wysiwyg-font-size-medium" style="font-size: 16px;">If you are still unable to recharge, try charging the Omni overnight, as this might be caused by over depletion of the battery cells. This should only occur if the Omnicharge has been left in a depleted state for an extended period of time. This process has been known to be successful in some cases after multiple attempts. If it does not work after the first attempt, unplug the charger, wait 5 minutes and plug it back in for an additional charging attempt.&#xA0;</span></p>
<p><em><span class="wysiwyg-font-size-medium" style="font-size: 16px;">Note: Remember to charge your Omnicharge periodically when not in use. We recommend fully charging every 3-4 months.</span></em></p>
