Really?). A zip bag contains the various adapter attachments: Apple 30-Pin, USB Mini, USB Micro, and a standard 5V Barrel connector. The other end of all of these adapter attachments is a smaller-than-normal barrel connector that plugs into the female barrel connector at the end of the spring cable. The other end of the spring cable is a standard USB A male connector, same as you would plug into a computer. There is also a mesh-bag carrying case.Sadly, I have to touch on two raze items right here:The construction of the USB spring cable and the adapters is nothing less than shoddy. I had to quickly convert to using a normal cable that came with the phone and tablet over the included spring cable. The USB A side of the power cord has trouble maintaining connection with the battery and the adapters have trouble maintaining connection with the device. While this nice compact cable would be a great boon to many, the poor quality makes it next to useless, with constant wiggling of the connections often needed for it to continue to operate.There is also a mesh, draw-string carry pouch. This carry pouch is just barely too small for the battery pack to fit in and allow it to close and there is no way to easily store the connectors and previously-mentioned faulty spring-charging cable. Then I thought, “Maybe it’s just meant to hold the adapters and cable!”… But then it’s hugely overkill and the battery pack itself is not included in the carrying. The carry pouch really ends up being more of a hindrance than a convenience.While both of these items are really secondary and overall not worth a star off. Anker may want to consider a better design and quality for the adapters and the bag, for example a carry bag that can securely hold the battery itself with a Velcro flap instead of a drawstring and a secondary pouch for the connectors. As for the connector cable, besides substantially-better construction needed, they might have better luck with adapters that go from Micro-USB to the other formats. That would allow the use of Micro-USB with no special adaptation and fewer adapters needed for the other forms.What I would honestly love to see is some way to have things plugged into this without the cable sticking out so far. Phone and Battery, back to back with a low-profile connection to each would be truly-portable charging.»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»Battery for breakfast, lunch, dinner, and a late night snack…Nobody can deny that the digital world of today is a power-hungry place. Charging stations have cropped up all over and it’s not uncommon to see folks’ phones plugged into the local wall sockets at coffee shops or bars or hotels. Phones and tablets are faster, brighter, and more powerful, but they eat batteries like mad. Even with an extended life battery clipped to the back or stuck inside, most people will find themselves running low at some point. That’s where an external charger battery comes into play.Let’s start with some numbers and quick facts:USB specification carries 5V (five volts). Officially, it carries 500mA (milliamps), or 0.5A. Running something at 500mA for one hour will consume 500mAh (milliamp-hours) of energy. Amps are a unit of DRAW – or “pull” – not “push”. If a battery has 1,000 mAh of capacity, it can have a 500mA draw for two hours. With 10,000mAh of capacity, it can support the same draw for 20 hours. The mA or Amp rating of a power supply (3A in the case of this external…

    Awesome portable power supply. For those readers that are reading this review on the Item page, this review is for the Astro3E 10000mAh charger. Since Amazon mixes reviews with all different “variants” of a product, and this comes in multiple capacities, this makes it hard to separate reviews.This product does what it advertises, and does it VERY well. It comes with a nice mesh case which I carry it in constantly, and a nice little coiled USB cord with a few tips. While these aren’t compatible with every device I own, I use it mainly to charge my phone, which is MicroUSB and included.Some devices I have tried charging: – I own a Motorola Droid 4, and I have charged the phone from dead to full over 4 times on a single charge. Android and Apple ports work, but on the Android port, the Droid 4 actually charges FASTER than the stock plug-in charger. My phone does not seem to mind. – An LG Ally charges on either port, but faster on the Android port. – A Nintendo DS Lite (with a compatible USB cord) charges on either port. – An iPod Nano 6th Generation charges on the Apple port. It does not respond on the Android port. I have charged this device from dead to full, and did lose enough capacity on the battery for it to register.I will update this review with more results as I charge more devices. I’m going on a few flights in the next couple of months, so this charger will gets LOTS of use.
