## Questions & Answers

**Q: Why is my power bank providing fewer charges than expected?**
A: A power bank loses 30%-45% energy as heat during charging due to cable resistance and internal circuitry. A full charged 20000mAh bank provides about 11000mAh-14000mAh to devices.

**Q: Why does my product recharge slowly?**
A: 1. Recharging to 50% within 30 minutes requires the use of a charger of more than 100W; an 18W charger takes 5 hours to fully charge;

**Q: Why does the displayed battery percentage number flash when charging?**
A: It is not a display screen malfunction, but a design feature of the product to indicate charging status.

**Q: What fast charging protocols does CUKTECH 15 support?**
A: OUT1 supports PD3.0, DCP and Xiaomi 120W charging protocols.

**Q: Can this power bank be taken on a plane?**
A: Yes, the power bank complies with TSA requirements (<100Wh) and is approved for carry-on luggage during air travel.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A power bank that maintains HIGH VOLTAGE with dual simultaneous outputs
*by K***Y on February 5, 2025*

I've been searching quite awhile for a compact power bank that can sustain power for two devices that both require 12V (one is a guided telescope mount and the other is a mini-PC for astrophotography). I have tried several, but despite their claimed wattage for 2 outputs being sufficient, I discovered that most power banks will drop the voltage down to 5V when you connect more than one device. So I was very happy to finally find that this CUKTECH 15 is able to maintain high voltages with both USB-C ports connected. As shown in my picture, I'm getting 20V from OUT1 and 12V from OUT2.My second image shows a screenshot from the CUKTECH website which showed me that it could do at least 12V across both OUT1 and OUT2 connected. Even though the telescope mount doesn't draw much actual power (so the wattage requirement isn't too high), it fails to operate at 5V, and thus would fail to work on those other power banks that advertised being able to do 20W on the second output, but would operate at 5V/4A rather than say 12V/1.65A.Be aware that the "newer" model of this power bank (still called the CUKTECH 15) which has an 85W max output, is UNABLE to sustain 12V when both USB-C ports are being used simultaneously. Only this model can accomplish this.

### ⭐⭐⭐⭐⭐ Fast charging!
