## Questions & Answers

**Q: the capacity of this  charger is 10000 yet it is mentioned in one of the comments that it can only charge up to 6660. why is that?**
A: The battery capacity is 10000mAh but not means it can have full 10000mah effect output energy. Because it will have energy loss when we charge the device through power bank.And the out put formula is 
     3.7V*10000mAh/5V*0.9=6660mah
 3.7V is the power bank's volt, 
 5V  is the phone's volt,
 0.9 is the energy loss ratio

**Q: Does it support pass-through charging?**
A: It doesn’t support pass-through charging

**Q: What is the input voltage range? can i use a 6v regulated energy source to charge this power bank instead of the 5v usb standard?**
A: You can use the USB-C port on the power bank to fast charge the unit itself. The USB-C port is both an input and output, supports fast charging in both directions.

**Q: Can you use both micro usb and type-c input ports simultaneously to charge the power bank quicker? thanks.**
A: No, it only supports single port recharging

### ⭐⭐⭐⭐⭐ Superb charger! Best value for money
*by B***Y on July 4, 2019*

Recently I lost my power bank onboard a flight. I was looking for a replacement that is lightweight and could handle at least 2 charge cycle for a combination of my phone collections, Pixel 3 and iPhone 8+, 6s and Oppo. First I bought Anker Powercore 20100, it was kind of bulky and somehow it stops in the middle of charges with no reason. I have to push the button on the side to start again. Also, Oppo charged very very slow before it stopped. No fast charge for Pixel. So the next thing, I ordered: Charmast 20000 PD/QC 3.0. I found it lighter than Anker, however, this one ran 3 charge cycle and got down to 50%. Oppo charged better than Anker though. I was thinking of keeping Charmast, since its lighter than Anker and smaller. But then I came to see Okzu 10000 has the same QC 3.0 and PD. So I got this one too to check out. Okzu has worked out the best so far! The unit is so light. Smaller than iPhone, sleek design and as of writing this, I am running my 4th charge cycle. I charged Pixel 3XL twice, one from 38% and another from 47% and it fast charged like magic. I charged Oppo, and it fully charged from 17% and then the unit shutdown itself. Then I charged iPhone 6s from 19% to 100% in about 93 min. And the interesting thing is, it still shows 2 led lights. I guess for <$20 this is the best one worked for me so far. I am going to return both Anker and Charmast. I am leaving a 5 star for this now, and I will adjust the ratings up or down based on how this unit performs over the next couple of months.
