Charging times for Xtorm solar chargers

Imagine being able to harness the power of the sun to charge your devices wherever you go. At Xtorm, we make this possible with our innovative Solar Power Banks and Portable Solar Panels. In this blog, we share all the information you need to maximize the potential of solar energy with Xtorm's solar products. Discover important factors affecting charging speeds and gain insights into the average charging times of all our solar products.

What factors affect the charging speed of solar panels?

Although Xtorm's Solar Powerbanks and Portable Solar Panels provide reliable power solutions, several factors can influence the effectiveness of the solar panels, just like any other solar panel. The three main factors are: seasonal changes, time of day, and cloud cover. For instance, in winter, the sun shines about 50% less powerfully than in summer, making optimal conditions for using your Portable Solar Panel occur in the summer. The sun's intensity not only varies with the seasons but also throughout the day. In the early morning and evening, the sun is lower in the sky, resulting in lower intensity. The peak hours for solar energy generation are typically between 11:00 AM and 2:00 PM. Additionally, thick cloud cover can affect charging speed by reducing the amount of sunlight reaching the panels. However, this doesn't mean you can't use your solar panel in winter, on cloudy days, or in the morning. It will just take a little longer for your devices to fully charge.

At Xtorm, we always use the latest technology to provide high-quality products. Xtorm's brand new SolarBoosters Gen '24 boast an impressive solar charging efficiency of 24%, compared to only 17% for older generation panels. This means that these new Xtorm solar panels perform much better in low sunlight conditions than other panels.

How can I store power for later with a Portable Solar Panel?

Portable Solar Panels do not have a built-in battery, which means they cannot store energy for later use. To charge devices, you simply connect them directly to the solar panel and let the sun do its work. However, Xtorm's Portable Solar Panels offer a simple solution to store generated energy for later use. By connecting the solar panel to an Xtorm Powerbank or Powerstation and charging it via solar energy, you'll have enough power on hand to charge all your devices in the evening or on very cloudy days. We offer various bundles on our website so you can obtain this combination at an affordable price.

How long does it take to charge mobile devices with my Xtorm SolarBoosters?

How long does it take to charge my Xtorm Solar Power Bank with solar energy?

Because the estimated charging times can vary a lot depending on the circumstances, we have done estimated calculations for 3 different scenarios:

  1. Perfect sunny day in summer
  2. Mostly sunny day in spring or fall
  3. Mostly sunny day in winter

We will not offer estimations for very cloudy days, because it is really not effective enough to charge through a Solar Power Bank.

In the table below you can see how long it takes to fully recharge your Xtorm Solar Power Bank:

It is even possible to charge two devices at the same time. However, charging then naturally takes a little longer because the output is split between two ports. The advantage is that you can simultaneously charge your smartphone and earbuds, so you can enjoy your favourite music without a hitch. Powerful outputsBoth USB ports give an output of 10.5W FastCharge and can thus charge several small mobile devices via solar power. With 5V/2.1A, you have enough power to charge a drone, GoPro, phone or tablet, for example, without any problems. Realtime brightnessThe LCD screen has two functions.
