## Questions & Answers

**Q: Has anyone used it to charge a laptop?**
A: I have. I got a pretty decent charge from it

**Q: Can I use it in any part of the world?**
A: Yes. I’ve taken it everywhere with me. Just make sure you have your adapter

**Q: How do you activate "always on" mode?**
A: I own a previous Xiaomi 20,000mah power bank that had that mode to charge/ power devices that draw too little current to keep ordinary power banks on. I do not know if this power bank has that feature. On the older power bank I own always on mode is engaged by pressing the power button twice. All the charge indicator lights will blink. I think it stays on for two hours at a time in this mode. I found this mode invaluable for charging my juul vape pen. It would also come in handy for something like string lights. More power banks should really include this feature.

**Q: Does this power bank support pass through charging. Meaning I can charge the power bank and draw power from it at the same time?**
A: I believe so.  The charge lasts a really long time.
