Camping, trekking, hiking and more - vacationing in nature is relaxing and sometimes exciting. From relaxing on the beach to white water rafting, there are also a variety of activities. Most of them are there: smartphone, action cam and smartwatch. But the batteries in these devices also need electricity when they are out in nature. That's why I've put together a few interesting power banks for you. From the power bank with crank to the power bank with solar panel, flashlight and radio you will find a lot of offers. In the following you will find cheap and good to very good rated models.
Before I get to the power banks, i.e. the crank devices with their own power storage, I would like to introduce you to two products that direct the dynamo current through to charge the device battery. That means, you connect your iPhone or iPad, the Action Cam or another mobile device and crank to charge its battery. They are particularly suitable as equipment for emergencies or a power failure. The first hand crank is small and something for the backpack. The second model is more for cars, campers and at home (e.g. for a power failure).
Of course, you have to take into account here that the power banks only bring a few percentage points to the battery level by cranking them. Therefore, they are more interesting for emergencies, such as a longer power failure or a multi-day or week-long excursion into flora and fauna and less suitable for everyday use and quick charging in the bus, train or at home. In addition, cranking the train could also cause one or the other irritated look.
Experienced and sporty hobbyists can, for example, connect the battery to their bicycle to build a dynamo with their own power storage or to be creative in another way to protect their own muscles. In addition to technical know-how, a good portion of creativity and ingenuity is required here. If the power fails at home for a longer period of time, the power bank can also be connected to the home trainer.
But there is sure to be a tutorial or two for this as well, which could serve as inspiration.
In general, there are a few things to look out for when buying:
In addition, it is worthwhile not always to fully charge the technical equipment and rather to charge cell phones and co. In flight mode so that it goes faster.
A power bank with a crank, i.e. a crank generator with electricity storage, usually also has other options for charging. So you can charge the external battery via USB and partly via solar panel. On Amazon there are even multifunctional devices that, in addition to the dynamo crank and the use of solar energy, are also equipped with a flashlight and a radio - some with an alarm clock, recording function and, and, and. The complete overview of the Amazon offers with good customer ratings can be found with this link. Below are a few examples from simple designs to all-rounders.
Almost a year ago I was able to present you the RAVPower RP-PB003 Powerbank with solar function. The external battery, which is equipped with a robust housing, offers up to 15.000 mAh, a charge indicator, the possibility of charging and drawing power via USB and a beautifully bright flashlight. I can definitely recommend the accessories for camping, hiking, trekking and road trips. But patience is required: With this model and most of the other models, it takes up to 7 days to fully charge the battery via solar. In an emergency, however, a (half) daily charge is sufficient.

Direct sunlight is also ideal there, but of course this is not always the case. This can also extend the charging time. Thus, these power banks are more suitable as a replacement and not as a primary energy source when the actual power bank runs out of juice.
It is also a good idea to charge the power bank outside in direct sunlight and not inside through the glass pane. In order to fully charge a power bank with a solar panel, it would have to be in the sun for more than 24 hours.
However, there is usually a residual voltage in power banks that can also be used to make an emergency call. If you want to be independent of the weather conditions, you should rather use a power bank with a crank or, depending on the equipment, charge the power bank at home before departure.

Which energy storage device would you not want to miss when traveling? Feel free to leave a comment and share with me and all other readers what will help you with charging the battery when you are out and about. Conventional power banks without special functions in the test can also be found here in the blog;)
Here at Sir Apfelot, where it is often about mobile devices such as iPhone, iPad and MacBook, some of the articles are of course also about suitable accessories. Here in the blog you will find, among other things, test and experience reports on some power banks. Because this is a Update from mid-April 2021 a MagSafe power bank for iPhone 12 models also plays a role. But I also offer you “classic” examples in the following list, i.e. those that you can connect by cable to your iPhone or another device whose battery you want to charge:
