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 leverage 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 Panel.

Travel light & ultra-compactEasily charge your devices when there is no power outlet nearby? You can now do so with this Xtorm SolarBooster! The compact and foldable solar panel fits in your backpack or handbag and easily connects to, for example, your phone or power bank and charges it. Enjoy green solar energy in an easy way, wherever you are. Simultaneous charging in a bright wayWith the two connectors, USB-A and USB-C, it is easy to charge your mobile devices. 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. First, it gives an accurate number of the output the SolarBooster provides to your connected devices. Second, it indicates the optimal angle at which to place the SolarBooster. When you rotate the SolarBooster, the number on the screen gets lower or higher, depending on how much sunlight it captures. Giving you the reliable info you need to get the most power from the sun!A 24% high returnThe two panels on the SolarBooster are made of monocrystalline solar cells. These more expensive, but better quality solar panels, are made of a single piece. As a result, the yield per surface area is maximum 24%, much higher than for polycrystalline panels. A monocrystalline panel also works well in lower sunlight and at both extremely high and lower temperatures. As a result, the 14W SolarBooster panels produce #MoreEnergy than cheaper solar panels. More solar energy to charge your devices! Taking it to sunny placesWherever you are; this Xtorm 14W Foldable SolarBooster always comes in handy. For example, charge your phone or earbuds with green solar power in the backyard, on your balcony or during a relaxing day at the waterfront. The compact and foldable solar panel is easy to carry in your bag or backpack. Resistant to splashesThe SolarBooster is rated IPX4 and has a splash-proof coating. So a little drizzle during a festival or camping weekend is no problem at all. The panel can easily withstand 5 minutes of rain splashes from all directions. Place it on the bright side With the integrated stand, the SolarBooster is easy to put down and ready for use in no time! It is important to use the SolarBooster outside and not inside behind glass, much less sunlight will be absorbed. Of course, the SolarBooster works best when the sun shines profusely and there is not a cloud in the sky. When it is a cloudy day, there is less solar energy to give to your appliances. On a perfectly sunny day, you get the most out of it. Pure energy boost from the sunUsing green solar power is a sustainable way to power your mobile devices. With this 14W Foldable SolarBooster, you can easily give #MoreEnergy to your smartphone for example, without using mains power. Via the LCD screen, you can easily see how much output the SolarBooster is currently giving to your connected devices. Give your devices a pure energy boost with the power of the sun!No sunburnThis 14W Foldable SolarBooster is safe to use thanks to Xtorm's comprehensive safety check. Both the SolarBooster and the connected devices are protected against short-circuiting, overheating and overcharging. The SolarBooster contains no batteries, so there is no risk of overheating or burning the panels, not even at high temperatures. Make full use of the sun, as soon as it shines! Carefree charging, in a sustainable way.
