Q: Can power bank solar-charged be re-charged by a regular power outlet?

Yes. Each power bank listed in our review recommends totally charging the device with a regular power outlet first. Then, you can opt to switch to solar charging in case you only need it.  The reason its ideal to use a power outlet first is that solar charging is slow and will take much of the time.

However, there are those solar chargers that are not power bank and do not store energy. Instead, they only transform energy to charge your device. Therefore, those devices cannot be charged by a regular power outlet.

Q: Why does outlet charging take a shorter time than charging from solar?

Several factors can help us understand the reason why they are like that. First, solar cannot be powerful than electricity that comes directly from the grid. That’s why outlet charging will always charge the battery faster. Secondly, climate change for the case of solar charging can alter the speed. For instance, during cloudy days, there is less direct solar energy, and therefore there will be a slower charge. But for the case of outlet charging, weather change might not alter the electricity transmission. So, they will charge faster.

Q: Do solar panels make the power bank bulky?

The weight comes from the battery itself but not the solar panels—however, it’s essential to know that power banks solar-charged are not so massive as people may think. The average weight for most of them is 1 pound or maybe a little bit high from one pound.

Q: Will the power bank charge my smartphone slower because of its Solar-powered?

No.  This is because some of the power banks comprise cables and a choice for a quick charge.  The battery capacity and output are what govern the charging speed.  The more the battery capacity, the more the charging rate and vice versa.
