    • Good thing, if not suddenly died

      posted by SergeyMazanov on 08:39:38 G7T 24/07/2013 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: Good little battery. Enough to charge the phone 1-2 times. Enough light weight, easy to carry

      Cons: Batteries suddenly "died" after a one year of use. The green light is permanent on, as a full charge. I disassembled device. There are 2 batteries connected in parallel. One of them is swollen. Also ON/OFF switch is very small and uncomfortable.

      Other: One year of use is not bad for its price

    • seems to be fairly well built

      posted by TheMarkster on 13:15:43 G3T 31/03/2013 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: Nice metal housing should be fairly durable. Can charge via USB with either the built in USB connector or with the included USB cable adapter. LED indicator light

      Cons: The built in plug sometimes slides back in when you are trying to plug it in to charge it. Not a biggie though since you can hold the plug out by hand while plugging it in or you can charge with the included cable.

      Other: For the price, and because it seems to be fairly durable, I think it is a good buy.

      Pros: Enought capacity to charge fully HTC Desire HD.
      In use more than 6 month. No problems.
      Small, lightweight.

      This device have relatively low capacity, but it vveery lightweight, very small.

      Cons: Worse design of charging connectors. This is a con.
      Tips:
      Do not forget special cable comes with device to charge it.
      Do not forget turn it off.

      Other: My recomendations.

      posted by FoxThrottle on 22:03:37 G10T 26/10/2011 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: - Small pocket size solid item;
      - Good black design;
      - Indication of the battery charging finished (red light while charging in progress, green when finished);
      - Charging with an USB port or external 5V DC adapter.

      Cons: - If you forget to switch off it after your phone charged, battery can discharging itself;
      - Real battery capacity may be less than 2400 mAh;
      - Possibly non-replaceable internal battery.

      Other: This charger adds some energy for most your USB gadgets and another equipment that powered by 5V USB voltage.

    • handy extra juice!

      posted by FiXato on 14:30:40 G7T 27/07/2011 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: * Easy to charge via USB * Plug in just about any USB-powered device * Bright LED indicator * On/Off switch * Retractable USB input plug * Large enough battery to fully charge my SE Xperia X1i * Compact size

      Cons: * The push-out input USB plug is pushed back inside when you try to plug it into a USB port. You need to push against the 'switch' to keep it in place while plugging it in. * the DC->USB cable is a bit dodgy. Since there already is the push-out USB plug to charge the unit, I don't really see the point of it either.

      Other: It does what I bought it for: giving my phone the extra juice at the end of the day when the regular battery has run out (at a lower price than a new phone battery). It's got a slick design, is portable and easy to charge and used to charge. A reliable emergency power pack at a cheap price that has saved me several times.

      posted by Phoxy84 on 03:07:56 G4T 13/04/2011 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: It's a nica small emergency battery pack which can be connected with USB. I use it in emergency's with my mobile phone. Just take your charging cable with you and power it on. You see that it works because the charging led on my phone will turn on.
      It works really good, in a few moments my phone had enough power to startup.
      it''s size is gooed, the pack just slides in my bag without taking a lot of space.
      It's useful that is can be charged from USB. I can charge the battery from my USB wall charger of pc.
      The capacity is good enough to give my phone some juice. I don't haven't tested how much it will charge my phone from zero.

      Cons: The build is a con. The extentable USB is very weak. When you put it in you computer is doesn't hold and pulls back in. Also the usb charger looks weak in the device.

      Other: A must buy for someone who wants to operate electronic gadgets outside for extended periods of time.

      Involvement Level: Expert (understands the inner workings)

      Pros: Small and compact- Fits into your pocket. Its even smaller than my mobile phone and still packs a punch of power. Strong design- The whole product is made of plastic however, it feel very tough and would take a lot of wear and tear to damage it. Even the slide out usb for charging. Charges and powers virtually anything usb. hasn't failed me so far :)

      Cons: There isn't any instructions that come on how to use it. Though it is fairly self explanatory itself.

      Other: A must buy for people who are going out of town, camping for a few days or even for some extra juice when its needed. You wont regret it

      posted by lindi on 05:16:12 G11T 28/11/2010 certificated customer

      Involvement Level: Expert (understands the inner workings)

      Pros: - Compact. I can keep both the battery and my PDA inside the same waterproof case and it's the USB cable that takes most of the space :-) This makes it very useful for mobile use. - Robust. The sliding USB connector is the only part that looked weak but has held itself together for more than a year. - Cheap. I bought two of these so that I can charge them in parallel. This is much handier than buying one larger battery that does not even fit to my pocket. - Can be charged from USB. This is the killer feature. I can charge the battery from my USB wall charger, USB car charger, laptop or PC. - Reasonable capacity. The advertised capacity of 2400mAh * 3.6V = 31 kJ is not that far off. Just by looking at how much my PDA consumes and waiting for it to empty the battery I measured 25 kJ after 6 months.

      Cons: - Incomplete documentation. It does not mention if it is safe to charge and discharge the battery at the same time for example. - Bright LED. The bright green LED annoys some people but on the other hand it is quite useful as an emergency light :-)

      Other: A must buy for someone who wants to operate electronic gadgets outside for extended periods of time.

      Involvement Level: Expert (understands the inner workings)

      Pros: Fully charged my iPod touch3.
      Very easy to be use and the dimension is quite small, make it the best partner for long trip.
      Easily charged through laptop USB port or any USB Charger.
      The LED indicators are usefull, (eventhough it is too bright)

      Cons: looks a little bit cheap at the first time (especially when the LED is on)
      The capacity printed is misleading. It couldn't be that much.

      Other: Worth to buy if you want to extend your gadget battery life.
