Veľké sklamanie. Mobil nabije,ale powebanku nabiť je zázrak. Vyskúšal som originál Apple a Xiaomi káble a adaptéry,taktiež nejaké random značky a nič nefungovalo na tento zázrak.

Velmi zle, vyskusal som 5 kablov dva adaptery a vobec sa nechcela nabit. Potom po precitani komentarov som ju zo srandy pichol do TV a zrazu zacala nabijat, tv ale napisala ze velky odber a odpojila usb port. Takze som musel vyhrabat praveky adapter a s tym mi to nabija. Mal som pocit ze mam fajn powerbanku ktoru nabijem ked nenabijam mobil. Prd makovy, pripravte sa na maturitu, ktory kabel s ktorym adapterom bude fungovat. Smutne neodporucam
Fajn design
Nenabijete modernejsiou nabijackou

Like all Alza Power products, made in China. It stopped working after a short time.

It works
Better get another one from the range, this one is really basic for charging devices with slow charging

Already several times a product from the "Alza" brand that stopped working after a short time. After a short time, a fully charged powerbank stops responding and charging the mobile phone (shows 0/4 capacity LEDs). After trying to recharge it again, it surprisingly wakes up and shows immediately charged to 3 /4. this is the first time it's been like this and it's not the cable. For me again a disappointment, this was the last "Alzaprodukt". I see no reason to buy de facto electronic waste that I can throw away in six months.
compact
definitely does not correspond to the stated capacity

lucky it didn't hurt anyone and it didn't blow up completely
served well for a year and a half
compact dimensions
power bank, already once claimed/replaced, stopped charging exactly 2 years after replacement/purchase
after 3 days from dead state it inflated
