Q: Questionwhat is the total discharging time of this model powerbank?

Asked 3 weeks ago by Rush2112.

• A:Answer Hi Rush2112, The total discharging time depends on the power draw of the devices you connect. This model provides up to 30W total output and offers three ports (USB‑C1, USB‑C2, USB‑A), and higher‑wattage devices will drain the battery faster while lower‑power accessories last longer. Because different devices consume different amounts of power, the discharge duration can vary widely.

Q: QuestionMy power bank for some reason does not charge my Garmin gps. It is 12 volt. I have never had this issue in the past. Please advise this is so strange it's a battery. Thank you.

Asked 3 months ago by Fritz.

• A:Answer Hi Fritz, Your Garmin GPS requires a 12V input, while the Energizer Ultimate Lithium power bank provides 5V via USB ports (even with Power Delivery, it only adjusts up to 9V or 12V for certain USB-C devices, not for 12V DC barrel connectors). This is why it won’t charge your GPS directly. You would need a step-up adapter or a dedicated 12V car charger for compatibility. --Energizer PowerPacks Service Team

Q: QuestionWhat is the total power bank capacity after energy loss so not 30000

Asked 5 months ago by RodolfoG.

• A:Answer Hi RodolfoG， Great question! The Energizer Ultimate Lithium 30,000mAh Power Bank has a rated capacity of 30,000mAh, but due to energy loss during voltage conversion (from 3.7V battery to 5V USB output), the actual usable capacity is typically around 18,000–20,000mAh. This means: You can expect to charge a typical smartphone (with ~3,000mAh battery) about 5–6 times. The exact performance may vary depending on your device and usage. If you need help calculating for a specific device, feel free to ask!

Q: QuestionCan this output only 5V, at 2.4 amps?

Asked 6 months ago by Sissy.

• A:Answer Hi MGL, Yes, one of the USB-A ports on this power bank supports 5V at up to 2.4A output. It also includes USB-C Power Delivery, which can deliver higher voltages (like 9V or 12V) depending on the connected device — but for basic 5V charging, you're covered.

Q: QuestionWhat is the minimum load required to keep this power bank on? I need to charge hearing aids and operate another device which switches on and off randomly. Is there a way to keep this thing latched on? Yes, I realize that would drain the battery over time.

Asked 6 months ago by Flatus86.

• A:Answer Hi Flatus86， This power bank may shut off when powering low-draw or intermittently active devices. For your needs — charging hearing aids and a device that switches on/off — we recommend switching to the UE30035C, which is designed to maintain output even under minimal load. --Energizer PowerPacks Service Team
