Rolling Square TAU 2 (2nd Gen) - Power Bank Keyring for Smartphones with Digital Business Card Feature NFC/QR Code, 2000mAh,Compatible with USB-C, Micro USB and Lightning, Grey

Great piece of kit,no need to carry seperate leads or charger,will give you around a 25% charge in average phones

Don't buy. Sooooo slow and will do my standard Samsung to 20 % but takes forever 😴. Just tried it again and phone went up 3 % in 21 mins 🙈. If only it was fast charge. Waste of money, don't buy 🙏

Great size for an EDC,

Very handy to have on keys incase you need a little charge to keep you phone from dying. fully charged it gets my iPhone 15 pro max to about 20% battery from 0%.

This is currently priced at £29.90. I like the idea behind it, but it lacks power...It only has a 2000amh battery so you will only get about 30% additional charge if using a new phone, so given the price and the size of others there are better options available. It is also quite heavy to keep on a key ring.

The most compact charger it's possible to find (and i have looked hard). There are slimmer chargers but none as pocket sized. It won't fully charge most modern phones but it will give about 25% which could make all the difference if your phone is running out of charge

I'm not sure I understand what they were trying to achieve when they came up with this? It's a mini power bank which is rather limited in 2024. 2000mAh slow-charge only, for attaching to a keyring? It's small but still likely to be pretty cumbersome on a keyring - especially if there's a car key on it.There's a technology out there that's called USB where the U stands for Universal. Why not use that? No, they've used a less common magnetic connection that needs docking charger instead. Hmmm? Charging at home only then, unless you want to cart the charger around with you.It has an NFC function for sharing information. Ummm, why not just use your phone?? Not sure I understand this extra?Look, it'll charge your phone up by typically over 20% but at the end of the day there are other options that are 5000mAh, maybe a third bigger, support fast charging, can be charged by USB and currently, a third of the price. I know which I would choose to carry with me.

A fantastic edc power bank. Super light with cables attached so great for a super light pack. First rate.
