## Questions & Answers

**Q: They exaplain what is "always on feature" and then they say after 20 minutes it will shut itself down. is 20 minutes = always?**
A: Hello, Thank you for reaching out. Our apologies for the confusion - the battery does not arrive in our "Always On" function, but rather in the standard "Auto Off" function, which turns off after 20 minutes of inactivity. If you wish to put the battery in "Always On", simply hold down the power button for 5 seconds - the battery's LEDs will blink 3 times to signify it has been switched from "Auto Off" to "Always On". You can read more here: https://www.voltaicsystems.com/always-on/We hope this helps!- Voltaic

**Q: Will it output the full amount of current (2.1A + 1A) while pass through charging?**
A: We are seeing 0.95 and 2.05A with both ports activated. Note that we only recommend the 2.1A port for use in solar applications.

**Q: Would a 6v solar panel charge the battery?**
A: Not sure, it was purchased to charge a cell phone.

**Q: has anyone hook this up to a solar charger and leave it on 24/7? will it cause a fire?**
A: In additional to the quality of the battery itself, this battery has a variety of protections (Short Circuit, Over Charge, Over Discharge, Over Current, Over Temperature) so that it can be safely charged 24/7.

### ⭐⭐⭐⭐⭐ Excellent for solar low power applications
*by P***O on January 18, 2021*

I own a V20 and a V50. These packs are fantastic for my radio-related applications because they are 1) always on and 2) have overcharge protection. I use them to power unattended low power radio beacons (WSPR if you are interested). First, the "always on" feature is very important because the low power draw of the (0.2 watt) transmitters isn't enough to keep other Li-Ion battery banks operating (they turn themselves off). Second, the overcharge protection is great because I can semi-permanently hook the V20 / V50 up to a 20 watt solar panel (with a 5v buck transformer with USB output). One of my beacons has been operating (off-grid, of course) for 6 months now without any human intervention. For my sort of application - low power devices that are solar charged - the V20 / V50 saves me having to purchase a charge controller and lifepo battery. Using the V20/V50 is both cheaper and less bulky (and easier to fit and wire up in a weatherproof box).
