Universal Portable Power Bank External Phone Charger with Ultra High Capacity

I bought this power bank for our holiday abroad and I have been so impressed on how long it last, I used it to charge my phone twice in couple of days and I still have 50% battery life left. Amazing

This is solid and well-made, a satisfying hunk of metal to heft in the hand. It's big, about the size of a 6" phone, but the capacity is nowhere near the claimed 20000 mAh. From a full charge it charged my Moto E with its 2390 mAh battery in about an hour and dropped to 52% charge. That means it would charge this phone twice rather than the expected (and claimed) six or more times! Still, that's good enough for most emergencies. It doesn't seem to have any LED that can be used as a torch. Although it's protected against short circuits it would also be nice to have some sort of cover over the ports to protect them.

It was really good when I first received, but stopped working after few months. I have only used few times, wwhen I needed it it was not working at all, very disappointing.

Most reviews so far are quoting specifications from the product description - instead of the actual performance that is provided by the unit. I took delivery this morning, charged it to 100% and then connected my p20 pro, which has a 4000mah battery, that was showing 48% of capacity. When the p20 pro reached 98% the krekco was down to 45%! The krenco had transferred just over 2000mah to the p20 pro - around 10% of its *claimed* capacity. Yet the krekco had said farewell to *55%* of its capacity! Nowhere near its claimed specification. No sign of a torch facility on this unit either, the tiny instruction leaflet suggested pressing the button 2 - 5 times but no light - and I can't see anywhere on the unit where the led is housed. I'll try the unit for a day or two to see if the performance level is consistent & update this review afterwards. As a prime customer I received a different 20,000mah power bank today (which I'll review - check it out) I'd watched the krenko lose its remaining power down to zero very quickly on the table using a low power dashcam that doesn't have a screen. So with the krenko at 0% I hooked it up to the new power bank which I'd charged to 100%. The result - the krenko was charged to 100% - using just a third of the new power bank's capacity. That says it all for me. I'm returning it, amazon say they'll refund and I don't doubt that, they're great with customer care. BUT! The ONLY way it can be returned is by self postage. No other option is available. Due to it being a battery I'll have to find a carrier that will accept it. Amazon will compensate for £4.75p MAX. Update! I was worried that I may well be out of pocket on this purchase but amazon customer service phoned me as requested and recommended 'parcels2go' to return the powerbank to amazon. I dropped it off at a local collection point and three days later I received a full purchase refund and 100% postage costs from amazon. Excellent customer service as always 😊

Great back up battery when you needed the most Huge 20000mah power with, 2 USB slots incorporated, you can comect 2 devices i the same time Not too heavy to take in the luaggage when you travel, ideal to charge devices on the move Bought this to recharge my son's helicopter 🚁 batteries when we play in the park

It works, but is definitely not 20k as advertised.

Nice size easy to use probably getting 2 and a half charges from a fully charged power bank whilst still using the phones. It has been invaluable whilst in NYC with teenagers. I would recommend

The good think is realy like the small screen. But for charge take lot . And the battery life is not the best.. from 1-10 i can give 7* thank you for fast delivery..

Ho comprato questa powerbank in previsione di un viaggio in Scozia di due settimane. Sono appena tornata, e posso dire con assoluta tranquillità che questa powerbank ha fatto al caso mio IN PIENO! Leggerissima ( più leggera del mio samsung a5 2017!), carica MOLTO velocemente (soprattutto visto che non credo supporti la carica veloce, almeno non mostrava l'avviso sul mio telefono), ed anche dopo un uso continuo (tutti i giorni, usata più volte al giorno per ricaricare ipad, cellulare, cuffie blutooth), non sono mai riuscita a scaricarla oltre il 60%! Consigliatissima!!! Unica "pecca" è la superficie LISCISSIMA, che non permette di appoggiarvi nulla sopra ammenochè non vogliate guardare l'oggetto schizzare stile "scivolo ad acqua" verso il pavimento. Tutto sommato comunque un gioiellino! Speriamo continui a fornire le eccellenti prestazioni di queste due ultime settimane (solo il tempo potrà giudicare).

un prodotto di ottima fattura da desing bello, manegevole, ricarico il mio huawai p10 fino a 5 volte. L'unica pecca la torcia, si accende appena ma tanto non serve pèer l'utilizzo per cui è stato concepito.........ottimo!!!!

Davvero un buon prodotto. L'ho caricato una notte appena ricevuto, l'ho usato già alcune volte ed ha ancora una buona carica. L'indicazione di carica in percentuale ti permette di sapere sempre quanta ne hai a disposizione senza avere brutte sorprese. (almeno spero) Esteticamente è ben fatto, sottile ed ha le dimensioni di uno smartphone. Un po pesantino ma ovviamente è 20000 quindi anche normale. Grazie a prime ricevuto, come sempre, nei tempi previsti.

il prodotto a prima vista sembra ottimo abbastanza sottile e con buoni tempi di ricarica peccato che la batteria non sia assolutamente 20000mAh dopo due massmo tre ricariche di un p10 plus è completamente a secco.

Spedizione nei tempi. La batteria è molto comoda, di dimensioni ridotte, sottile e molto leggera...comodo lo schermetto con la percentuale di carica...tuttavia a mio avviso credo che la capacità sia inferiore da quella dichiarati di 20.000 mAH...credo sia tra i 10.000-15.000.
