I love Anker products and feel like they are higher end and safer than other batter chargers, especially with their LG Cells and not some big gel pack inside the unit. This unit is working exactly as designed and does deliver battery power through two ports. It takes a long time to drain it. However its a lot heavier and larger then the PowerCore 10,000 with only one USB charging port (which I own), and duhh, right I'm getting a bigger pack, but its just enough bigger to make it less useful and less portable. Way less chance of it ending up in a purse or pocket. So its relegated to knapsacks and other longer duration travel situations and less around town. Don't get me wrong, its a good product, just be aware of its size and weight, but if you can live with one port and 1/3rd less power, the PowerCore 10,000 is a better size (see my update below - as long as you don't mind it in your knapsack, the extra power is awesome).
Also the button layout and charge port and indicators are in odd places. The layout is better on the PowerCore 10,000, but the 10,000 only has one USB charge port.
Update: Its larger than the 10,000, but man it seems to pack plenty of power, and it is a workhorse - I just bumped my review up to 5 stars after a few different business trips. I just took a business trip and from the start of the day until the end of the day I barely moved this thing 1 bar on the power meter and it kept my phone at 100%. I didn't even bother to bring an auto adapter for the rental car, I just used this instead. A flight, then 3 hours of GPS usage on back country roads, and then heavy hotspot usage while onsite with a customer. By the time I got to the hotel 15 hours later it will still 3 of 4 dots on the power meter and my phone was at 100%. In real world use its awesome to not have to worry.

ANKER: BEST PORTABLE CHARGERS EVER. PERIOD.
I've had Anker products for the past 3 years and they are the best! I still have 2 of the older portable 2nd Gen Astro 3 chargers for 3 years and they are still going strong! Needed an upgrade so I got the Powercore 15000 redux for my iPhone; also bought the Powercore 20000 for work. I had to do a time lapse for 4-1/2 days using 2 GoPros at Times Square; because lack of AC power and the sucky GoPro batteries, I used the 15000 Redux and 20000, being able to continuously power both GoPros for 10-12 hours straight!!!So w/ the 15000 I can charge both my iPhone SE and my bluetooth headphone... the charger lasts over 5 times before I recharge the charger again.Don't get the overpriced crappy Mophies (they suck and I went thru 3 of them before I switched). Ankers make the best products. (Also own a couple of their USB hubs too.)

Le dimensioni sono molto contenute ed il peso non è assolutamente eccessivo, quindi si può tranquillamente portare in giro anche in un borsello di piccole dimensioni, non è assolutamente invasiva, nella confezione c'è anche una custodia di stoffa a retina in cui riporla quando non si utilizza per preservarla da graffi e quant'altro.
L'ho testata in ricarica e permette di ricaricare uno smartphone (ho provato con Samsung A8 e Sony Xperia Z3) almeno 4 volte in maniera completa. E lo fa molto velocemente. Le due porte USB 3 per ricaricare permettono di ricaricare due dispositivi contemporaneamente, ottima cosa per una power bank così compatta.
Ha un prezzo importante, è vero, ma gli euro che costa li vale tutti. La Anker, almeno per quello che mi riguarda avendo ormai molti suoi prodotti, conferma di essere un'azienda affidabile e di qualità...
Sono soddisfattissimo dell'acquisto.
