The solar panel technology is changing rapidly. This change allows for portable solar
chargers today with foldable design. In the field of solar chargers, there is an
incredible variety of features, accessories, and quality between products.
The first phone with official case is Jolla, powered by Sailfish OS.
Today you can choose between a super efficient charger (monocrystalline) or lightweight
charger (CIGS thin film).
Photovoltaic cells based on thin layers are a good option for mobility because they
are lighter. But they have an efficiency (10% to 12%) lower than that of monocrystalline
silicon and are also less durable.
If you are looking for a lightweight and affordable solar panel, CGIS of thin film
cells are a good choice. If you want a more robust loader, choose a single-crystal
It is larger and heavier, but also more durable. As technology improves,
monocrystalline panels are becoming more portable.
Before buying a solar charger for mobile phone, you should check the battery capacity
expressed in mAh. Ideally, this capability must be greater than the capacity of the
smartphone battery to recharge. It should also monitor the year of marketing.
The latest models of solar panels are more efficient and can charge the battery faster.
It must still rely usually ten hours of sunshine to recharge the backup battery completely.
That is why most solar chargers can charge the smartphone sector too.
A good alternative to solar chargers is a shell battery or an external battery .
External batteries are cheaper, lighter and can recharge a smartphone 3-6 times.
Solar Charger: the criteria for choosing
A solar charger is an effective accessory to recharge a smartphone, a GoPro or GPS
in suitable conditions of sunshine. It is a useful accessory for outdoor activities:
hiking, sailing, camping, camper, climbing, mountaineering, kayaking …
Here are three essential criteria before choosing a solar charger:
1. The output power: it is expressed in watts (W) and clearly indicated for each charger.
The Goal Zero Nomad 7 has a power of 7 W. The output power is important but you also
learn about the amperage of USB outputs. The RAVPower 15W charger has a USB 1 Amp output
to recharge the smartphone and a USB output to charge 2 amps tablets. 2 A USB port iPad
charging faster than the port with 1A.
2. The weight: this is an essential criterion for most outdoor activities like hiking or
climbing. By cons, it is not important for the boat or camper. Some solar chargers are
very compact and lightweight.
3. Versatility: it is an important consideration if you want to charge multiple devices
such as a smartphone, tablet, GPS, GoPro, etc. If you only want to charge your mobile
phone, this criterion does not count and a simple charger may suffice.
4. Compatibility: This is an obvious criterion. Most solar chargers are compatible with
most smartphone models.
