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.

Very disappointed

I completely understand that this is not a charging station but for what I spent and the charge that I get from it , it’s not even worth carrying. At 44% on my phone I connect and I get to 45% . I spent a decent chunk of change and it’s not even worth the postage it would take to send it back .
