Review: Brilliant device - This is a truly brilliant device. I bought the higher capacity one and am so pleased I did. It’s a manageable weight and seems to last forever! No loss of charge if not used and will fill an iPhone several times over - useful if you are taking loads of photos and using the battery up more quickly than usual. It’s incredibly quick to charge and the convenience of not needing separate leads is huge (it’s yet to be seen how well the built in leads last). I can walk around using my phone as it charges if needs be. Or sit over a coffee while it slurps up the juice for its battery. My daughter snaffled mine when visiting her far away so on return home I immediately bought myself another. I wouldn’t go anywhere without it now.
Review: Excellent. - Very good power bank. Seems well made. Gets rid of need to carry multiple cables. It’s fairly slow to charge itself but it charges devices plugged into it quickly. Only thing that would make it better is if you could charge the power bank and use it charge devices at the same time but that functionality is not supported.

## Questions & Answers

**Q: Why your power bank seems to drain quickly than expected?**
A: Power banks lose energy during charging due to heat and voltage conversion, typically supplying 60%-70% of their power to other devices. Therefore, a fully charged Charmast 20,000mAh power bank can deliver about 12,000-14,000mAh to your devices.

**Q: Can this power bank be taken on airplanes?**
A: Carry-on allowed. Do not pack in checked baggage.

**Q: Does it work with small devices?**
A: Yes. Enable low-current mode for headphones, watches, etc.

**Q: Is it normal for the portable charger and phone to get warm while charging?**
A: Yes. Some warmth is normal during charging and use due to energy conversion. If temperatures exceed 45°C (113°F), stop use immediately.

**Q: Is it compatible with laptops?**
A: No. Use a 30W+ laptop charger instead.

Not as good as Anker, seems to lose power over time, but a lot cheaper. Will definitely last a few years
