FAQ's

Q: How do I turn my Nano on?

A: Press the Dark Energy logo on the front of the Nano. That’s your power button. Once it’s on, the Nano will stay active while charging a device, then automatically shut off after a short period of inactivity to conserve power.

Title

Q: How many times will this charge my phone?

A: The Poseidon Nano delivers about 50-70% of a full phone charge, depending on your phone’s battery size. It’s built to give you a reliable boost when you need it most.

Title

Q: How come the MagSafe charging won’t work on my phone?

A: To use MagSafe charging, your phone must support MagSafe wireless charging. Most iPhones, iPhone 8 and newer work — but if your case is too thick, made of metal, or not MagSafe-compatible, it can block the connection.

Title

Q: The Nano gets warm when charging — is that normal?

A: Yes. All power banks generate some heat while charging, especially during wireless charging.

Nice sturdy magsafe charger… pairs well with my solar charger

Great Product!

This little battery bank is a life saver. Easy and convenient to carry with you and adds enough juice to get me through the end of the day. My phone is my business and now with this battery bank I never have to worry about being away from a charger. 👍

People Can’t Read Product is Good!

Description States the product would only charge 40-70 percent of battery. Yet people complain when they don't get a 100 percent of a charge for their phone, it's not going to do that so why leave one or two stars? Charges fine according to what it states it should do and compared to what one review stated it is a good quality battery and doesn't feel cheaply
made. Bought one looking at buying a couple more in the near future!
