Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

- Reviewed in the United Kingdom on 9 July 2025Colour Name: GreenVerified PurchaseIt was good while it lasted. I charged up this power band 3 times on holiday when I tried to charge the power bank a fourth time a flashing light came on intermittently and it just would not charge. I left it on charge for about 6 hours and it ran down the 0. I tried to contact the seller 3 weeks ago and no response.
What a waste of money

- Reviewed in the United Kingdom on 7 June 2025Colour Name: BlackVerified PurchaseIv had it for about 3 weeks now will charge my phone comfortably for a day. Will charge my phone around 2.5 times and this is more than enough. It does take around 5 hours to go from zero to 100 on the portable charger but that's not problem for me. Personally. Started charging my laptop when the portable charger was at 69% and my laptop was zero. Fully drained the portable charger and my laptop went from 0% to 72% and that's more than enough I say.

5.0 out of 5 stars Gute Powerbank mit schneller Ladezeit
Colour Name: BlackVerified PurchaseDank der 45Watt Ladeleistung ist die Powerbank schnell wieder voll, natürlich nur mit einen entsprechenden Ladekabel.
Mein Alte Powerbank brauchte immer lange zum aufladen und ich musste gefühlt 1 Tag Laden.
Bei dieser waren es ca. 1% pro Minute Laden mit 45Watt Ladegerät.
Die Optik und Haptik ist Gut, und alles macht einen Soliden Eindruck.
