FAQs

It depends on your smartphone’s battery size. If we assume you have a device with a large 5000mAh battery, this means a 50000mAh portable battery should charge your handset 10 times. Of course, this is only in theory. There is always some energy loss, and your phone may use some energy while being charged. This means it should be more like eight to nine charges.

Most basic portable batteries tend to charge your devices relatively slowly. If you want some faster charging, you should look out for Power Delivery in the features. Battery packs with PD can usually charge more advanced devices like tablets and laptops. These can generally reach 60W charging speeds or higher. You might also want to consider power banks with AC outlets, which can charge at 150-200W or more.

Solar power banks can work, but they are very inefficient and tend to charge very slowly when using sunlight to juice up. Furthermore, they tend to come from unknown brands we don’t really know much about. All the best portable batteries seem to omit solar capabilities, unless they are large, external ones.

Not really. Even the most potent power banks are limited to a certain degree. The best portable chargers can usually handle about 200W, which would be your most significant limitation. For example, most desktop PCs use far more than 200W. This means you shouldn’t be able to power said PC, even if you have a full battery charge and want to use the computer for a few seconds.
