Sleek and Enough Battery
I was given this product as part of testing campaign. I was very happy to receive it. Unlike others I have used previously, this was very sleek and thin. Does not take up much space at all. And the battery lasts long.

Perfect charger
I received the onn. Portable Battery 4K mah in black and it is perfect for on-the-go charging. The chargers is so small and compact that it can fit right into your pocket. The charger is sleek and the charge that it holds is very impressive. I was able to charge my phone on the go.

It is ok
The size is nice and it slim so it fits in the pocket well. The mah not much but should be enough for one time power up on the go. I was charging it for long time but the light didn't go off so i am not sure it works properly

Works and Lasts
I was happy with the capacity of this device! Used it during a 12 hour road trip in a car and worked just as it should to charge phones, earbuds and other devices. Worked as expected and would reccomend!

Great for outdoors or electrical outage
I received the onn. Portable Battery 4 k mAh in black. It comes with a charging cable and with a USB mini-A input, not a USB mini-C input. I wish the power was higher as it gives one charge at a time. Otherwise it works fine. I like that it is thin and compact, easy to carry anywhere. Great for outdoors or in case of electrical outages.

Une bonne solution !
Nous avons essayé le chargeur sur différents appareils. Google et Android. Dès sa sortie de la boîte il était possible de charger un appareil. Pour recharger le chargeur cela à pris moi à d'une heure. Nous avons apprécié l'avoir sous la main quand nous sommes partis au chalet où il n'y avait pas de prise électrique pour recharger nos téléphones!

Easyyyy to use
The ONN. 4K mAh Power Bank in black is a good, reliable option. It's compact and provides a decent amount of charge for your devices when you're on the go. A solid choice for staying powered up without taking up much space.

Works well
Works as intended and for price point to mah size it's fair value. Simple design and easy to operate. Would include a flashight in future with seperate operating battery.
