Are SunSaver power banks safe to take on planes?
Yes, most airlines allow power banks under 100Wh (Watt-hours) to be taken as carry-on luggage, but never with checked-in luggage. Because the SunSaver 10K is 37Wh and the SunSaver Classic is 59.2Wh, they are safe to take on most flights, but please check with your airline for their specific rules.
Can I charge my SunSaver power bank with a USB power supply?
Yes, all SunSaver power banks feature a USB input so they can be charged very quickly. To ensure the fastest possible charging, please make sure that your USB power supply and USB charging cable Amp rating match that of the power banks input.
Does the solar input of SunSaver power banks really work?
Yes, but a bit slowly. Because the solar panels are just over 1-Watt, and the batteries are relatively large, they are going to take over 50 hours of direct sunlight to fully recharge themselves.
But just one day of good solar charging can provide enough power to give a smartphone a decent charge.
Isn’t exposing power banks to heat bad for them?
Yes, temperatures above 30° Celsius can deteriorate the performance and longevity of lithium-ion batteries. That’s why it is recommended to monitor the temperature when charging SunSaver power banks via solar, and to not expose them to high temperature environments, such as on the dashboard of a vehicle.
How long do solar power banks last?
Most power banks with Lithium Ion batteries are rated for around 500 cycles of their battery from flat to full. So, how long the power bank lasts for depends on how much it is used. Power banks can last for over 2-years for the average user.
The life of a power bank also depends on the usual temperature it is stored at, because at extreme heats, the power banks battery will degrade. Because solar power banks are likely to be exposed to heat more often than normal power banks, they may not have as long a life.
