The sCharger-8 (S8) will perform better in hazy or low horizon sunlight conditions over the S5.
The S8 and S14 are a must for disaster situations so you can stay in touch with first-responders, authorities and family. The S8 can sustain 3- 5 people with charge.
Using a solar charger can be a lifesaver. Every time a disaster hits, we get a huge demand for orders. So please be prepared.
Undecided for serious hiking? The S8 weighs in at about 13 ounces. It may be a bit heavy for long term hiking, but it is the perfect choice for short term hiking and backpacking. With this higher power, you can share the charger with your hiking party.
If you have multiple devices and want to save some cost, we suggest the S8. For more assurance with disaster prepping and need more power, you may want to consider the sCharger-14
