Swiss Charger GPower
Hi
I have been using the Swiss Charger GPower for more than 3 months now,
Pros
- Does the job of adding extra battery backup
- adds 40% more battery backup
- give the phone a bit of protection
Cons
- the sleekness of S2 is lost
- makes the phone heavy a bit but extra battery time is worth it
Issues I am facing
- I have a S2, GT9100G, 2.3.6 stock none rooted device, i used to find that the USB connectivity with my widows 7 64 bit was not stable,
- just after 5 min the device would not work and the driver will show "device not responding"
- removing the USB cable, and reconnecting brings back the connection
- to hold the connection, I had to keep my finger moving on the Phone screen looked as if when phone goes to sleep, the USB conenction was not waking up
I contacted the Samsung service - and as a solution the reflashed my handset, things worked fine and my phone was connecting normally with no failure
but
when i put it back in the Swiss charger and try to connect, i have the same issue - so the original issue was not with the device but with the charger
has anyone faced a similar problem? what is a possible solution?
Will appreciate a reply as changing between covers might take its toll on the phone
Cheers

hie i bought this swiss charger yesterday in india..
it started well showed 2 dots of charge level...
i utilised it to charge my sgs2..
bt aft dat it didnt showed anything..
its not showing battery level even aft keepin on charge whole night with my cell..
pls suggest me how to charge o replace this product...

Dear Dholyabhai,
When you press the power button of GPower, it shows the blue indicator that it is charging, the amount of charge at hand is indicated by the number of blue indicators. but after some time the indicator does not show up (I guess this is to save power wastage). you can still see the phone being charged in the Phone charge indicator on the notification bar.
when put the phone with Gpower to charge, it looks both get charged and since the battery now is 1500+1650 the time taken goes up a bit (depends on the charger trickle rate)
Cheers

can someone post pics of this

Today bought this device in Spain (25 euro), was looking for it before in Ukraine, but only available by preorder.
Nice looking while SG2 inside, soft touch quite durable as for me.
Everything else you may find on above youtube video. Definitely Gpower "must have" device for long range traveler as me.

that swiss charger does look ok , have you ever thought about one of these
http://www.amazon.co.uk/TeckNet®-Du...1?s=electronics&ie=UTF8&qid=1335310567&sr=1-1
or even a desktop charger and spae battery??
that usb battery pack i linked should be good to charge your sgs2 over 3x from empty on stock battery

That one also good which i use now (see screenshots). The big advantage here that you can insert any capacity NiMh accumulators and also ordinary unrechargable batteries. Moreover if accumulators inserted they are charging slowly via sunlight panel + you got long lasting flashligt packed with 5 diods. Tested one time on 2500 mah NiMh accum. constant lighting time more than 24 hours.
So now I got extended battery 2000 mah + swiss charger 1500 mah + extra accum set 2500 mah = 6000 mah total power.
I bought this device 3 years ago in my city and still it selling here. Price is around 35$. It comes with commonly used adapters for Nokia, Ericsson, etc phones + microUSB+miniUSB.

Monoprice 2800mAh portable battery box

I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.

shouldn't this be in the accessories forum?

Hate the ones that plug right into the phone like that. Pretty much makes the phone a huge pain to use. I would rather spend the extra money and pick something like this up

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

huh?

It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.

WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.

OK well, turns out that this batt back is crap.
Updated the main post.

This Gadget Is a Handheld "Power Plant"

No release date as of yet but I'll be on the look out for this...
UPDATE: THE CORES ARE NOT RECHARGEABLE. THAT'S A LET DOWN FOR ME. HOWEVER, I DO SEE THE MARKET FOR THIS.
When we say "two weeks to a month" of power, we're referring to the ability to charge your phone (tested on an iPhone 5) once a day for two weeks. But for people who charge their phone around 20% battery life (instead of when the phone is completely dead), like many people, the charge would last about a month. That's where those numbers come from.

WOW...that seems great....

But, it is way cheaper to recharge using a normal battery pack. I see a reason this technology exists, but, its calling is not recharging batteries.

What are people supposed to do with old pods?
This seems a bit bass awkwards
Spelling errors courtesy of my phone

200$+ for the power plant.

I'm not sure it is for me and you on a daily use basis where we can plug in etc...but if you are a long distance traveler and in areas where there ain't no plugs, 10 of these in a bag would last you a while in remote areas. Pretty much anyone that goes to, reports on or whatever for long periods of time, I can see how this would be a god send.

So it's a fuel cell basically. Probably enclosed. Fuel cells run off hydrogen typically gained from splitting water molecules. More advanced fuel cells can gain a higher efficiency rate when mixed with other chemicals.
I'd be interested to see if you could crack one of these babies open and just refill it with water. I know they already have water-based chargers. Using pure water would probably reduce the efficiency and longevity, but its water... refilling is still easy.
Most companies that are doing these "fuel cells" are really just trying to find a way to nickle and dime the customers. Companies don't want to introduce "free energy" by just filling up a bottle with water. They want to split the modules and sell you just the hydrogen/fuel mixtures.
Would be nice to just buy a fuel cell that lasts a few years. That would be worth it. But the cost of this device + refills <> electric? Are they trying to make a "cheaper" solution to plugging in to the wall every night (cause they should be) or are they marketing it as a "convenience" device with a high price tag (seems like it).

It looks like whether or not this is even going to get released is in question.
This is a comment on the product page @ Brookstone:
"Ordered from brookstone during the CES promotion with a shipping date of july its now september and acording to customer service they dont know that they will ever get them. Theres even a nifty term for that vaporware."

Or just bring one solar panel charger and an external battery pack that you can charge during the day.

This one looks like a better deal to me. If I needed a kit for wilderness trips, this would be the one.

I always carry a Goal Zero Nomad 7 in my bag. It's never failed me when I needed it. I have the battery pack accessory, so I can keep it charged up for times when I need a charge at night, or it's just too rainy. I've been thinking of upgrading to a slightly larger panel. Anyway, my point is that portable solar panes are great, and they don't cost anything but the initial investment.

I have a 12,000mAh power supply with 3 USB ports that I use quite often, I got it for $35-$40.

I looked into this a bit more and found out that the fuel pods contain butane. They are asking $10 a pod (pre-orders get a free one).

Too expensive for me, but would be great alternative to solar power for long camping trips.

nice one!

My Review :
I got this power bank for £29.99 from amazon and i think its worth every single penny. And I really like the high quality build of this power bank with matt finish. It charge my phone in 1 hour 45 minute from 0 to 100(S6 ) and This power bank’s high power capacity makes it great for charging multiple devices, especially considering its USB charging speed 2.1A output.And it allows me to charge my phone 3 time from 0 to 100.
The first thing you notice about this unit is it’s size ,weight and it cool designee . Believe me at this point I thought there is no way this device roughly the size of a smart phone could possibly jump starter my car. I've always used a heavy, bulky and cumbersome 18kg jump starter/battery pack, so it's hard to believe something measuring just 18 x 8.5 x 4.5cm and weighing 617g (vs 18kg!) can perform the same role - but it does!! I tested this unit on a standard car battery AND a van battery and both started perfectly ON ONE CHARGE!!
I've now used a few of these compact jump starters, been impressed by the performance of them all and they have each started our 1.6 Citroen Berlingo, 2.0 Diesel Renault Laguna and 1.4 petrol Megane. Of them all, however, this one seems to be the best, most powerful and it's the only one to include a red warning lamp to indicate a hazard - essential for roadside breakdowns.

Review: Intocircuit 15000mAh powerbank w/ pictures

This is a review of a power bank from Intocircuit - http://www.amazon.com/gp/product/B00OSYLXKU
As phones have been getting more and more powerful over the years, portable battery packs for smartphones and tablets have been gaining popularity. There’s many different brands and variants available, and today we’re going to be having a look at a 15000mAh power bank from the company Intocircuit.
The power bank itself comes in a small box with some product information on it regarding the amperage and capacity, and inside there’s also a USB-cable and a small pouch to put the power bank in. The accessories are of decent quality and definitely are nice additions to the power bank.
So when it comes to the actual power bank, it’s made out of a combination of plastic and brushed aluminum – it really looks nice and a bit different compared to other brands. The power bank has 2 full-size USB ports that are rated at 2.4A, a MicroUSB-port that can be used to charge the power bank, along with an LED and a small LCD display that show the amount of battery that’s left.
When it comes to the actual capacity I must say that it’s pretty much spot-on, as I’ve managed to charge my Yoga 2 tablet (capacity: 9400mAh) and my Z3 Compact (capacity: 2500mAh) using it, before the battery of the power bank was fully drained. The recorded output current while hooked up to my Yoga 2 was stable at around 2A, and with a quality USB-cable reaching 2.4A should be certainly possible.
The main negative thing that I’ve to say about this power bank is the fact that it takes a long time to charge it up once drained, but that’s due to the higher capacity and other power banks such as the Xiaomi 16000mAh suffer from this as well. Charging the power bank 0-100% takes nearly a day, and therefore it’s a good idea not to let it drain completely before charging it.
So conclusion time – this is a pretty decent power bank for the price and it looks and performs great, and is comparable to other brands that I’ve tried in the past. The capacity is correct and the charging speed is decent, although charging the power bank itself takes some time. This is certainly a product that I do recommend if you’re shopping for a good power bank!
Pros:
- Good battery capacity and power output
- The included accessories (pouch, micro-USB cable)
- Decent build quality, and the power bank looks and feel great.
Cons:
- Takes a long time to charge up
Note that I was provided with a review unit of the above mentioned product, but that does not affect my review as it is solely based on my own opinion and experience.

Depending on how much your Raspberry Pi draws, let's say 1A, I would say about 11-13 hours at most.

Nice review. It's always good to have a back up power bank with you especially during a trip.

Can you charge the battery pack at the same time as it is charging other devices?

I'm not entirely sure about that as I've not tried it, but I think it may be supported.
