So the Charmast is lighter and cheaper. And will be delivered in 2 days instead of 18th July for the Imuto for me.
I doubt it has 20000mAh capacity.
Review shows the actual weight is 400g
https://amzn.asia/d/0icXoPs3INIU 25000mAh 100w powerbank is just 475g, and have been tested efficiency rate reached nearly 80%, so around 400g for a 20000 mAh is reasonable
Just to note, Anker 20000mAh 87w powerbank with build in cable is just 440g, I think 20000 mah powerbank over 500g may be a bit too heavy?
I've been using this Charmast power bank for the PINECIL soldering iron (https://pine64.com/product/pinecil-smart-mini-portable-solde…) every few days for 2 years now. Never missed a beat. Happy as. It's a no-brainer for 40% price of Xiaomi's similar one.
Avoid this one.
It can't sustain 100W charging. Even at 18W phone charging levels (9V 2A) it only gets 60% of the rated capacity.
I've tested quite a few Charmast models and none of the have the advertised capacity.
Same goes the for the imuto X4G linked above. While it does have the rated capacity (unlike the X6G), the cells are garbage and it can't sustain 100W.
If you want a quality but affordable power bank, wait for a sale on something from INIU.
1 hour sale btw
what was the sale price last night?
