A part of the review has been auto-translated.
It came in a regular shipping package, no bubbles, although a double one. Luckily, it was intact, only one corner of the plastic packaging was broken. Also included in the package was an European standard travel adapter: too bad it doesnt work for me - its for people coming to Europe from the US, or UK etc. But I still appreciate the gesture! It works well both ways - as a charger and as an external battery. So far I have only managed to measure the current as an external battery for my cell phone (Redmi Note 10 Pro) - about 1500-1600mA/h (from Li-Ion 26800 7200mA battery). There is still some space in the slot for a longer battery - for protected 26800, or up to model 26900(unprotected), I guess. The silicone (rubber?) band is too tight, even when using its both end holes (tried with 26800 battery). Im not sure how long it will last, if using a thicker battery? Overall: very good product and a price/quality ratio!
The best charger.
