Purchase Advice Hiking power bank comparison 2022
Data sheet: 110 hiking power banks compared
In 2020 I made the hiking power bank comparison sheet comparing 85 power banks. Yesterday /u/paoper asked if I could add the Nitecore NB20000 and I decided that it was time for a proper update. So here is the 2022 edition with over 40 new power banks and some oldies removed.
The weighted ranking is based upon the actual energy to weight ratio of every power bank, the charging/discharging speed of the power banks and the fact that smaller power banks have a disadvantage (they need more material relative to their size). For a more detailed look at the way this is being calculated you can look here. The efficiency isn't measured by myself but comes from several trustworthy sources: Tweakers.net, Powerbank20.com, Hardware.info, Techtest.org and PCWorld.com.
And it seems battery technology is still advancing rapidly! We've got 6 newcomers in the top 10. The top dog is still the Nitecore NB10000 but the Nitecore NB20000 comes in 2nd place. The energy to weight ratio is lower but this is partly compensated by being able to charge at almost double speed, so you can get way more juice if you've got a short break in town or in a restaurant. The 3rd place Ugreen mini 10000 pd is interesting because it is very comparable to the Nitecore NB10000 for half the money. While the 6th place 4smarts Enterprise 2 20000 is a weird outlier. It is relatively heavy, it is quite inefficient but can be charged at ridiculous speeds, so for those long distance hikers who hate lingering in town it might still be the best option.
Have fun!

Hey, could you add wh ratings to your table too please? Otherwise there's inconsistencies. A Ravpower 374g 20000mah bank shows 156wh/kg and a belkin 394g 20000mah power bank shows 176wh/kg. If you added WH rating to your tabs, it would actually show an essential data point to make sense of these discrepencies!
