JETech 10,000mAh Portable External Power Bank, Battery Charger, 2-Output, Black

This is fantastic for my kids and teaches sharing. My 9yr old is in charge of keeping the power bank and ensuring it is fully charged and then must use it to help 7yr old to keep tablet running as well as his own when out and about. It is able to charge two devices at once thus keeping both kids happy. Perfect for going on holiday or out for the day. 10000 mAh is very large capacity, great value for money. Lovely compact design and makes my 9 yr old feel very important. I'm sure it will come in handy should my phone ever die on me when out and about too. Take the stress out of life and put kids in charge of back up power supplies, they love it.

After a week of using this bank to keep my phone topped up and trying to keep track of how much I was using I estimate that the usable amount of power in this pack is around 7500mAh. While it's not the full amount advertised this is still enough to charge most phones 3 full times... Or about 12 hours of extra screen on time on top of the 4 the phone had initially. This is great for such a low price. I don't have a charge rate reader but this is definitely similar to a wall plug on the 1A port and will charge a phone up while the screens on with the cable included, I don't have anything that requires the 2.1A port so I cant attest to it. It takes a long time to charge with a regular 1A wall plug, expect it to take around 10 hours. It does support higher charging rates though at 2A, so if you have a tablet charger or a fast charger this will be almost halved. Onto the feel... It's heavy! It's thin however and fits in a mens pocket very nicely. The metal feels great, and makes it seem incredibly strong and look executive, much more expensive than it is , albeit slippery to hold. I got this for a 4.5 hour flight which is roughly a full phones screen on time these days and it excelled, the led indicators are very nice to have, each led almost represents a phones charge. The led flashlight is very bright and continues to work after the bank can't charge the phone anymore. Auto shutoff works well and should keep some extra juice where other batteries would ebb. I recommend this wholeheartedly. It's price/performance is fantastic and the capacity alleviates any charge anxiety you might have in your travels.

This is such a useful device. I've charged my mobile phone and my wireless mouse from it while I was abroad at work during the day. I don't think I managed to take it under half the battery capacity in one day, but I did make sure I recharged it when possible. With two USB ports and a set of lights to show the remaining power, this is a basic power bank. It's also small, smooth and easy to store in any bag. It's not clunky or cumbersome. It has a great battery life. Really, anyone with a moderate dependency on technology should have one. This will charge phones, mice, keyboards, pretty much anything that can be charged via USB. We've entered an age now where this type of item is almost a necessity.

i would never be without this power bank feels good in the hand good quaility materials and charges my samsung galaxy s2 4 times from when its empty on a single charge i am very pleased with its overall performance it can also charge my playstation vita all being its a little slow to do this ..but eventually does it as expected i bought it primarily for my phone and it does that great it also charges my portable blutooth bose speaker without any trouble still leaving enough charge to charge my phone twice over!! its an all round great versitile product the inbuilt led is quite handy to ...although not needed much holds its charge for at least a week ....which is great for power cuts as well highly recommended...i bought a second for my mum who for whatever reason never seems to never have her phone charged up when i need her .....now there are no excuses hehehe

Pleased with powerbank but connector supplied does not fit my Samsung Galaxy S7- (although did state is suitable for Samsungs) just as well I had a spare from a previous powerbank which I have to use instead!

This is a really solid item with a quality feel. Quite weighty so perhaps not the best for pockets but it's portable enough. It comes with two different USB ports which means you can charge 2 things at the same time. One port is marked 2.1A and one is marked 1A. As far as I can tell it just affects how quickly an item recharges and therefore how much juice is used up in the pack. The most impressive thing about this item is the amount of backup juice you get. It seems to have more than 2 full charges for my iphone 5c and I reckon it could even do 3 or 4 at a push. I've not been disappointed by this product.

I bought this recharger about a week ago and started using it for the first time yesterday. It recharged my iPhone 6 without any problem and used 25% of the charge. The recharging time was also quite good. So I assume I should be able to recharge my iPhone at least 3 times depending on how low the iPhone battery level is at the time of recharging. Apart from the the weight of the battery (I suppose it is because it is a heavy duty recharger) I think it is a good recharger and I like the fact that it also has an inbuilt torch which is handy on holidays. If I need a smaller light weight recharger then I just have to buy a different one. For the price, I think has been a good buy and I hope it continues to be for a long time.

Bought this for my 86y/o mum who is going into hospital on Thursday and was concerned about charging her tablet while away from home, thus staying in contact with family. It arrived sooner than expected, giving her time to work out how to use it properly before she needs it. It's really simple to use and is a nice weight so that you can't forget it's in your pocket. The lights are a really good idea to show the amount of charge available, and it has the advantage of being able to charge 2 devices at once. It's taken a big weight off her mind. I would recommend it.

Tengo un Jiayu S3 Advanced y he recibido este maravilloso power bank. Tiene 2 puertos USB, uno de 1 A. y otro de 2'1 A. He probado el cargador con el cable que lleva de serie en el puerto USB de 1 A. y carga igual o más rápido que el cargador que lleva de serie mi mvl. Solo recibir el producto ya viene con la mitad de su capacidad de carga, he puesto a cargar mi móvil desde un 40% de batería, y me lo ha cargado entero en hora y media aproximadamente. Lo he probado 2 veces más, y va genial. Solo dos aclaraciones: La primera es que tampoco pesa tanto como dicen muchos (como mucho igual que mi móvil... Esto no es tanto) Segunda, en mi móvil tengo una batería de unos 3.000 M.A. aproximadamente y me lo carga unas dos veces la batería "entera" e incluso creo que me da para un poco más... Y rápido... A diferencia de otros cargadores... Por lo que en vez de 10.000 M.A, quizás tiene una capacidad de 7.000-8.000 miliamperios reales, pero ya es lo que yo necesitaba. UNA COMPRA Y UN FUNCIONAMIENTO PERFECTO. Supongo que esto es lo que les interesa a los que quieran adquirir uno. Que cumpla su función y cargue perfectamente. Pues esto lo teneis asegurado.

Snel geleverd, goed van info daarover ingelicht. Netjes bezorgd.

Die Powerbank besteht außen rum komplett aus Metall und fühlt sich sehr wertig an. Der eine Knopf ist sinnvoll belegt (2 mal Tippen für Taschenlampe, einmal Tippen zum Einschalten der Powerbank und gedrückt halten zum Ausschalten), wobei ich persönlich die Taschenlampe nicht benötigen werde (trotzdem nett). Die Anschlüsse und der Knopf sind aus Plastik, fühlt sich aber nicht billig an. Die Powerbank ist etwas schwer, was aber bei der Kapazität kein Wunder ist, dafür aber unerwartet klein. Passt problemlos in jede Hosentasche! Auch gefällt mir, dass die Anzeige für die verbleibende Kapazität (4 LEDs) nicht zu sehen ist, wenn die Powerbank aus ist, sondern hinter dem Plastik versteckt ist. Die LEDs sind auch bei Tageslicht hell genug, um etwas zu erkennen. Eine Anleitung liegt in vielen Sprachen bei - unter anderem in nicht ganz korrektem, aber trotzdem gut verständlichem Deutsch -, listet aber nur grundlegende Funktionen und Warnhinweise auf. Braucht man nicht wirklich, eine Powerbank bedienen ist jetzt nicht direkt schwer. Gut gefallen hat mir die Verpackung. Alles in schlichtem Karton, trotzdem ziemlich schick verpackt. Das beiliegende Kabel macht auf mich keinen sehr langlebigen Eindruck. Ich habe mir hochwertige Kabel dazubestellt. Funktioniert natürlich trotzdem ;) Wenn die Powerbank lange hält und die Kapazität stimmt, würde ich sie wieder kaufen. Sollte sie in kurzer Zeit kaputt gehen, werde ich die Rezension aktualisieren.

Dopo le tante recensioni lette mi sono convinto all'acquisto e devo dire che rispecchia esattamente ciò che cercavo e quello che era descritto. La batteria è grande esattamente quanto il mio Huawei P7, non proprio piccola, ma non ne cercavo una compatta. Il peso invece mi ha sorpreso, è pesantuccia, ma mai quanto il portafoglio pieno di monete, quindi ci sta da portare in giro. D'aspetto è molto fine e sobria, i materiali sono buoni e non ci sono note negative nelle rifiniture, la zona delle prese e quella opposta sono fatte di un vetro simile a quello per cellulari. La torcia è li per ciliegina, fa una discreta luce conica e direzionale. Lo stato della batteria è indicato da 4 piccoli led blu, che trovo una discreta soluzione. La durata non l'ho ancora testata a cicli interi ma sembra buona. Ho potuto testarla con un paio telefoni e si è comportata diversamente, a chi caricava velocissimo a chi come un normale caricatore. Sicuro dipende dalle componenti interne e dal cavo che si usa. Per ora soddisfatto dei soldi spesi, però ripeto non velocissima sul mio terminale.

Oggetto ottimo e spedizione veloce come da tradizione e serietà che contraddistinguono Amazon! La batteria è ottima sia nei materiali che nella costruzione. La torcia a LED inoltre è un plus non da poco, peccato per peso e dimensioni non propriamente contenute, ma entra tranquillamente in tasca e nella borsa non da alcun fastidio. La carica è abbastanza veloce, grazie anche alla porta da 2.1A (anche se non è dotato di tecnologia Quick Charge sia chiaro)...qualche dubbio sui 10.000mah dichiarati in quanto appena arrivato ho messo in carica il mio Moto E con una batteria da 1980mah che dal 9% circa al 100% ha spento due dei 4 led luminosi che indicano la carica totale della batteria,cosa magari imputabile al fatto che la batteria anche se i 4 led erano accesi non era proprio al 100% di carica ed ha bisogno di qualche ciclo di ricarica prima di arrivare al massimo delle performance. Tuttavia ottimo rapporto qualità/prezzo visto che con 14€ circa vi portate a casa una 10.000 Mah (ammesso che siano reali) e con delle caratteristiche niente male, tuttavia se volete prodotti più preformanti vi consiglio sicuramente di aggiungere una 10ina di € in più e virare su prodotti di marche come Anker, Aukey o RAVpower.
