Review: Fast service! Fast delivery!! Quick response with problem!!! - First I bought this Anker power bank for myself, I love it because it is small, very light, no cord, just plug in and the power is enough for a day. Because I’m very happy with it, my son and his friend each bought too. After using almost daily for over a year, it stopped working. I ordered another one right away because I could not find anything better. It came the next day, very impressive!! In the meantime, I claimed defective with the non-working one. Luckily it is still under warranty,. In a few days , after claiming the defect one, Anker sent me the replacement. Very fast!! It is essential for me to carry this Anker power bank everyday. So I will keep the new one I ordered and the replacement as a backup too.
Review: Small but mighty - Soooo, I’ve had this for literally years! It’s super sturdy and compact. It charges somewhat quickly. It’s not heavy and it’s very aesthetically pleasing.

## Questions & Answers

**Q: Why is my power bank providing fewer charges than expected?**
A: The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker Nano Power Bank offers an estimated 2,750mAh to 3,500mAh to power devices.

**Q: How can I estimate the number of charges for my device?**
A: To estimate charging cycles, use this formula (Power Bank Capacity × 0.65) ÷ Device Battery Capacity ≈ Number of Charges. For instance, charging a 3,000mAh device using a 5,000mAh power bank would offer approximately 1.08 charges.

**Q: How can I make the charging connection more stable?**
A: Since the Lightning connector is foldable, it's best to charge in a stable position to maintain a secure connection. For example, hold the phone in your hand while charging rather than placing it in cluttered environments such as a bag.

### ⭐⭐⭐⭐⭐ Small but mighty

Soooo, I’ve had this for literally years! It’s super sturdy and compact. It charges somewhat quickly. It’s not heavy and it’s very aesthetically pleasing. The device itself might get warm while charging your phone. It also takes a while to charge the device, but I can get about a whole phone charge and a half out of it!

### ⭐⭐⭐ Great functionality but Questionable Durability
*by M***E on February 14, 2025*

I have always stood by Anker. Have two other power banks that throughout the last 4 years saved my butt while out camping. Naturally, I bought this one for my girlfriend who bc of work often runs out of battery and does not have access to a power outlet. She loved the size and color and having the extra battery available. Functionality is top tier as when plugged into the phone you can barely feel the weight and size and will fully charge her phone. However, after 5 months, it just stopped working. Just like other reviews mentioned it. It is fully charged but does not charge a phone anymore. I suspect it must be related to the charging port having to rotate to operate instead of being fixed. Anyways, I would've given it 5 stars if it wasn't because the Durability was definitely not up to par. Hopefully, it is just a product problem and not a brand quality problem.
