This Product: Easily the best balance of power to weight ratio. I tried several others and they were heavy, clunky, and felt pretty cheap. Or they were small, but lacked multiple ports, charged slowly, and ran out of juice to quick. This on the other hand is designed extremely well. Best of all, it is small and light weight enough to keep in my messenger bag 24/7 all the time. Essentially, it does the job of the massive power banks sacrificing the perfect amount of power and heaviness in lieu of portability. Portability is exactly why I want a product like this any way. Plenty of power for multiple devices, rapid charging, IQ technology ALL in one compact design. All at less than $20.
Here's why I love Anker... They make excellent products and if you ever have an issue with them, they take care of you. Period. So, five stars for the company based on numerous products I have purchased from them. One other product (Anker Robovac) had a minor issue pretty late into to the 18 month warranty. Send them an email on a Saturday, they responded Sunday, had the replacement part in hand on Wed (shipped all the way from LA to DC)
They are durable, dependable, and can hold a significant charge for their size. This charger is on the heavier size, but it is still fairly light and nonintrusive to your space. It has two ports to charge devices with and both can be used reliably. I keep it in my backpack along with a slew of cords so I'm always prepared.
The battery charge is shown by four lights on the face of the device. That's where my only complaint with this item comes in. I wish there was an actual number to tell you the charge instead of just few blue dots. Minor complaint, but a complaint nonetheless.

If you're familiar with the Anker brand, you would be very familiar with the experience of unboxing this product. The blue & white cardboard box contains the PowerCore 10400, a MicroUSB cable for recharging purposes, and a mesh bag to store the device in when not in use. Out of the box, I was a little surprised that the power bank only showed 1 LED illuminated when I pressed the power button on the side, typically these show 3-4 LED's and arrive with a bit more juice, not a big deal, just an observation. The design is very simple, but I couldn't think of any way to improve it, so in this case simple is good. Black plastic casing with a simple ANKER brand name on the front, a power button along the left side, and on the top 2 USB output ports with PowerIQ technology (more on that later), and a MicroUSB input for recharging.
I thought that because the power bank arrived nearly depleted, that I would finish the job by having it recharge my iPad Mini 2 until it was dead. Once it was completely dead, I plugged it into a 2.4A USB charger through my USB multimeter so I could monitor its performance while charging and capacity. The PowerCore 10400 is capable of recharging using a 2.4A charger, and my multimeter agrees that it does pull this amperage to recharge. This is great, because it will charge much faster than a charger capable of using only 1A. After about 6.5 hours, I checked on the status of the battery to find that it had shut itself off after being completely charged, and my multimeter reported having passed through 10434mAh of power to complete the recharge. Pretty spot on with the capacity that is being advertised.
The USB ports on the PowerCore 10400 have PowerIQ technology, which means that they willl automatically detect the proper current needed to charge your device safely and quickly. In my testing it was capable of recharging my more power hungry tablets as well as my not as power hungry mobile phones quickly and without either the phone or power bank becoming hot to the touch. With a maximum of 3A output across both ports, this is a perfect power bank to have on hand to recharge both a tablet and mobile phone at the same time.

I have an Sony xperia z5 premium. It manages to give it a full charge in just over an hour (with an Anker related USB)! Then still have about a third of energy left.
It does take a few hours to charge, but anyone who uses portable chargers knows to charge them overnight and charge them after every use.
I could be lucky but I dropped the charger into a sink and it still works perfectly too!
I use Anker for everything it sells as you know your are getting immense quality at a ridiculous price compared to more well established companies. I have reccomend and even purchased this item as a gift for a friend. Will be upgrading to a larger battery for my holiday next month.
PRO: Ottima capacità, che si è dimostrata dalle mie misure consistente a quella dichiarata. Ottimo rapporto capacità/volume e capacità/peso. Ricarica molto rapida anche di due dispositivi contemporaneamente
CONTRO: Non eroga tensioni superiori a 5V
PREZZO E CONCLUSIONI: Le prestazioni sono veramente ottime, con l’unica pecca che erogando solamente 5V non si sfrutta la ricarica rapida di alcuni dispositivi. In compenso la tensione è veramente stabile dall’inizio alla fine dell’autonomia residua,sempre al di sopra dei 5V, e, anche se non è molto chiaro nelle istruzioni, non ho problemi ad utilizzare entrambe le porte contemporaneamente, con telefoni che si ricaricano assorbendo fino a 1.5A ciascuno.
Venduta a circa 27€ (Settembre 2016), non è la più economica powerbank da 10Ah che potete trovare, ma è una delle meno esose tra quelle valide e che veramente mantengono ciò che promettono. Dopo averla provata l’ho consigliata ad un mio amico che si sta trovando benissimo, e non posso che consigliarla a tutti voi.
NEL DETTAGLIO:
PRIME IMPRESSIONI: La powerbank è interamente di plastica opaca nera di buona qualità, ha una forma allungata e smussata. La costruzione solida e l’aspetto monolitico, interrotto solo dal pulsante sul lato e i quattro led sul frontale. Ingombro e peso sono nello standard per una powerbank da 10000, essendo d’altronde vincolate dalle dimensioni delle celle al litio che la costituiscono, è qualche millimetro più sottile di altre powerbank di dimensioni analoghe.
Molto buona la sacchetta per il trasporto, delle dimensioni adatte a tenere la batteria e il cavo, che a sua volta è più lungo (60cm) di quelli forniti da molti altri produttori. Mi è piaciuto molto il fatto che si può utilizzare la powerbank senza toglierla dalla sacchetta, facendogli da “cover” e soprattutto evitando il rischio di perderla o dimenticarla in giro, mi è piaciuto meno il fatto che, rispetto ad un’altra Anker da 20000mAh che uso ormai da mesi, la sacchetta in questo caso non è proprio aderente ma un po’ più grande della powebank.
CAPACITA’: Come al solito il produttore indica la capacità totale come somma di ciascuna delle celle all’interno della powerbank, che solitamente hanno una tensione nominale di 3.7V. Per utilizzare questa energia attraverso lo standard USB la powerbank fa una conversione al suo interno. Per determinare quale si la capacità effettiva e quanta energia sia effettivamente disponibile sulle porte USB ho effettuato dei test di scarica, a 5V, con un assorbimento costante di 1A. Ecco i risultati, in cui riporto anche i risultati in Watt, unità di misura più corretta per valutare l’energia che la powebank promette, quella che possiede realmente e quella effettivamente utilizzabile:
CAPACITA’ DICHIARATA: 10,4Ah a 3.7V = 38.5 W
CAPACITA’ MISURATA: 12.5Ah a 5V = 32.5 W
Dal confronto tra i due valori si ricava un’EFFICIENZA dell’85% circa, lo standard per questo tipo di adattatori. “Ma quante volte posso ricaricare il telefono?” C’è bisogno di un’ulteriore conversione, questa volta a ritroso, effettuata dal dispositivo, solitamente con un efficienza dell’85% circa. Restano quindi 27.6W, ossia una “CAPACITA’ DI RICARICA” di circa 7.5Ah a 3.7V, il numero che finalmente potete confrontare con la capacità della vostra batteria. Ad esempio, potrete ricaricare 3 volte un iPhone 6s, più di 2 un Galaxy S7 Edge, o effettuare una ricarica completa di un iPad Pro da 9.7’.
In sintesi i miei test rivelano un’ottima prestazione della powerban.
PRESTAZIONI: Dalle diverse prove fatte sono emersi ottimi risulati. La tensione è molto stabile, e non scende mai sotto i 5V neanche all’ultima tacca di autonomia. Nessun problema in questo modello a superare 1A di assorbimento con tutti i dispositivi con cui l’ho provato: nella foto mostro il mio samsung A5 2016 caricarsi alla assorbendo il massimo che può sui 5V, cioè 1.5A. La powerbank non scalda affatto, la potenza erogata rimane costante anche verso la fine della vita utile, anche dopo 5 ore di utilizzo consecutive.
Durante la ricarica, invece, la powerbank arriva ad assorbire oltre 2A se il caricatore lo permette, consentendo una ricarica completa in circa 4 ore. Utilizzare un caricabatterie meno performante significa lasciare la Powercore attaccata alla spina molto più a lungo.
