    Pros: This is a product that gives you about 1,5 times the normal battery usage on your cellphone. It works well.

    Cons: I tried to charge my phone AND the "battery" at the same time, but that did not work well for me. My phone got charged, but not the extra battery I wanted and needed. So I learned that I had to charge them separately.

    Other: It works well, and I don't regret buying the product.

    Involvement Level: Expert (understands the inner workings)

    Pros: Good extra battery when you don't have time or possibility to recharge phone. Indicators always show how much energy left in battery, so you will know external battery health. Easy to use. Phone fits inside perfectly. Covered by rubber, so easy to hold, not slippery. Recharges from 15% to ~85-90%. Dont need to take out phone when you want recharge phone.

    Cons: Maybe price is little to high. I don't think its 2800mAh. Indicators is way to bright. Easy to push accidently start button when holding in pocket. With phone inside its big and heavy. Hard to press power and volume buttons.

    Other: Its worth to have it, when you need a extra battery.

    Involvement Level: Expert (understands the inner workings)

    Pros: Good material quality. Easy to fit the phone in it. I don't think it's really 2800 mAh but it's a least 2000, which is good and nearly doubles the battery capacity, when you are outside. It also protects the phone very well. I dropped it a few times (although it has a nice grip) but there was no scratch on the phone.

    Cons: It's big, heavy and makes the phone look ugly. That's why I usually keep it in my handbag and use when necessary.

    Other: It's good.

    Involvement Level: Expert (understands the inner workings)

    Pros: It really saves the day when you are running out of battery. Depending on how you use your phone it can give you from 1 to 1,5 extra charges on the phones battery. The material is good and the mechanism to open and close works fine. The case it comes with is also nice and protects the device. You can use it later for traveling and storing.

    Cons: The blue lights at the front of the device are really bright and it bugs me a bit as they remain ON all the time it is charring the phone. They should either make it much less bright or make it turn of after a short time (and keep the charging on of course)

    Other: Two other friends of mine have bought the some one after I showed them my battery case.

    Involvement Level: Expert (understands the inner workings)

    Pros: - Allows you to charge your phone on the go from 0 to70-80% - Really easy to use. Just put your phone in it, turn it on, and you're on. - It has a backstand. - Strongly built. - Surface is grippy.

    Cons: - Takes long time to fully charge. I tried different power supplies, 5V, 12V, 1A, 2A.... Still takes too long get all the blue lights up. Best to charge it overnight. - Output power is low. If you're phone is on, and doing something that is battery-intensive, it will not charge, and will make your phone REALLY hot. - Also, low output power will make your phone charge somewhat slower than with a normal charger.

    Other: I'd buy it again.

  • is good, but isnt perfect

    posted by pedrolima11 on 19:18:16 G6T 01/06/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: the product is very good, can leave the phone running for more than 36 hours, the aparalho loads fast, simple and works perfectly.

    Cons: The cover does not fit perfectly on the device, turn it upside down can occur to break the tip of the charger and the device falls. Do not hold the top of the device, it gets loose on top, it is risky to turn it upside down and fall. The LEDs are lit when you connect the external battery to conserve battery power and could disable the LEDs only light up when you press the button. It takes about 8 hours to fully charge.

    Other: I am use every day and I like, but be carefull.

    Involvement Level: Expert (understands the inner workings)

    Pros: Doesn't make phone as bulky as I first thought. Fits good around the phone and replaces any rubber protection. Looks good and goes hardly unnoticed.

    Cons: Cannot charge phone fast enough when screen and gps are on. Hard to find the right speaker volume. Button can be hard to press when in a hurry.

    Other: This is an S2 only battery pack. I would recommend a big external battery (8000mAH+) if wires aren't an issue to you. This is more versatile. If you definitely do NOT want any wire I would recommend to look at a bigger battery first. I have one of 3800mAH and is more bang for your buck (around 9 euro).

    Involvement Level: Expert (understands the inner workings)

    Pros: Charges the battery just like the original charger, not heavy at all, once you get it, it might seem that it's huge, but once you attach your phone into it, you realize that it's not so big at all

    Cons: It takes about 4 hours to charge up to 80%, it doesn't charge more than that. It doesn't have any more cons.

    Other: I recommend it, because I use it all the time, and it's been there for me all the times I used it.
