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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing and well made *by L***M on March 24, 2026* Those voltaic batteries are a beast.

Very simple to use, just plug in your device and its on! Easy to charge, great quality. Very happy with it. ### ⭐⭐⭐⭐⭐ Excellent Quantity *by J***K on October 23, 2025* Expensive, but perfect for my project that uses a Solar panel to keep battery charge while continuously providing power to small esp32-c6 controller that is controlling & powering a small water pump. Be aware that you need at Solar panel of minimum of 6V, 5W to charge this powerbank when you are also powering a separate device. if you just need to charge the powerbank then 5V solar panel will work. ## Frequently Bought Together - Voltaic Systems V50 Always On External Battery Pack with Dual USB Ports - 12,800mAh - Voltaic Systems V75 Always On External Battery Pack with Dual USB Ports - 19,200mAh - QILIPSU 6pcs 3/4" NPT Cable Gland Waterproof IP68 Nylon Cable Pass Through Cord Grip Connector Strain Relief Wire Grommet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/16752855-voltaic-systems-always-on-v50-battery-pack-13-400mah-48wh](https://www.desertcart.gr/products/16752855-voltaic-systems-always-on-v50-battery-pack-13-400mah-48wh) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-25*
