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.

Brother I got a similar equipment and is not as great as you pretend to be.
Sure the price is cool, you find it with 5 dollars on wholsales but I bet it doesn't have 12 Ah, if it has 10 Ah is good!
Second: the lights are not indicating the right amount of energy recharged.
I discharged completely, and started to charge with an 700mAh charger and the blue lights went on in a 2-3 hours interval and this is not possible.
Also is not possible as you say to recharge 12 Ah battery with 1Ah recommended, in just 3 hours as you mention.
This device needs like 10-12 hours with 1000mAh to make it full, and as I said the light indicators are not precise.
When I first got it, It had some power in it for test I supose, but it was showing all 4 leds lighten up. I powered my 33% Samsung Tab 2 7inch and started to charge till it reached 77% and then died!
I put it to recharge! In few complete cycles the life time will improve, but I don't think is able to recharge a 4Ah tablet 2 times! If is getting one time is perfect! Not with the tablet open, at least!
Another thing people should know is they should use their original cables, the connectors don't fit on my tab, and on an old Sony Ericsson phone. Both of them are the wrong size!
The design is nice, the price is good, but I don't think is a good battery pack!
Another thing people should know about it, is not multitasking. If you plug in a Phone and a Tablet in the same time, is dying fast, so.. you must choose!
I recommend this product for his low price! Is not so big either, but the cables and adaptors are junk.
Good luck guys!

Usually these batteries are of poor quality

Everything's from China

But everything's made in China?! (j/k, I know what you mean.) Most of the stuff sold on the ecommerce b2c sites are of the Shanzhai variety).
But isn't that always the case, you get what you pay for.
When I bought my Note 8, they offered me a deal to buy the Samsung 9000mAh power bank for about 600HKD, which is about 85USD. Expensive yes when compared to the typical cheap China stuff, but then again, I don't relish the thought of battery acid exploding on my leg. Though some might. I guess.

[Review] Kmashi 15,000mAh Battery Pack

Overview
I recently got a Kmashi 15000mAh battery pack and I have been loving it. 15 Ah is a lot of juice for all devices I have, and I can always count on this to have some juice left. It is not just the numbers that amazed me, but I have used it for days without my charger with me. I can charge my OnePlus one and Galaxy Note 8 twice, and still have juice left to charge my iPhone and S6. This is an amazing product for people who travel a lot.
Specifications
Capacity - 15000mAh or 55.5Wh
Input - 5V/2A
Output 1 - 1amp 5V
Output 2 - 2amp 5V
Size - 81*156*21mm
Weight - ~450g
Real world performance
I have used this battery pack with two phones. I took screenshots of the battery input received from this battery pack. The first image is for OnePlus One and the other is for Galaxy S6. The battery pack doesn't support quick charge 2.0 and the maximum output is not as high as I expected it to be. The input rate measured was lower than the listed output on the battery specs section, but it definitely charged the devices pretty quickly; so, I am not complaining.
Experience
I have always wanted a battery pack that wouldn't die on me when I need it the most. I have had a 5000mAh and even a 10000mAh battery packs before this and they would die on me after two devices max. If I have to remember to charge my battery packs too, then I know for sure it is not working for me. I got this 15000 mAh battery pack from Kmashi in hopes of getting a battery pack that I can throw in my bag and forget about it. The battery in this is huge, and there is minimal loss of battery when the battery is not being used; therefore, this battery pack will keep on going with you. I have travelled with this device and my OnePlus One without my charger for 3 days, and I never missed my charger.
For all the travel lovers, keep in mind it is not a small or thin device. It is almost 3 times thicker than an iPhone 6. It is a heavy product, which you might not wanna carry in your pocket. It has 2 USB ports, but that has a catch. When you use both the USB ports together, the battery outputs a total of 2 amps, which means 1amp from each port.
In order to charge this battery pack, I used a 2.1 amp USB wall adaptor (not included in the box). The battery pack takes almost one night to charge from zero to full. It is not easy to sleep with this charging beside your bed, as it's blinking LEDs are very bright. They can brighten up a room more than any night lights you have seen. Putting an electric black tape on them while the device is being charged is a good solution.
Pros
Large capacity battery
Feel and finish is all plastic but doesn't creek
2 USB Port to charge
Cons
LEDs are very very bright
Scratches easily
Long charging time
No Quickcharge 2.0 support

Tronsmart WC2F 36W Dual Ports USB Wall Charger review

Tronsmart is a most popular manufactory in mobile phone accessories, especial in certified Quick Charge 2.0 charger. I have already tested one charger from them before, but now, they have just released more chargers with more powerful features which you can’t resist.
In this short test I will test Tronsmart WC2F which features 2 quick charge 2.0 port for fast charging 2 devices at the same time, both port can reach maximum of 15V/1.5A each.
You can check out more features, including where you can buy this amazing charger from their official website at: http://www.tronsmart.com/products/tronsmart-wc2f-36w-dual-ports-usb-wall-charger-black
Let’s see what we got here.

There is not much to talk about the packaging, it’s simple and environment friendly. At the back of the package, we can find their company address, phone number and email for support.
Inside the package, we will have a charger, 2 USB cables, 1 manual, 1 VoltIQ sticker.
Here are our charger, naked.
Yes, there is also a manual for a charger, in case you don’t know how to charge your devices, you can open this manual, they will show you.
Let’s take a closer look at the charger. At the front of the charger, we can find Tronsmart logo, a small indicator light.
At the back, we can find the charger specifications, as we can see, it can charge at 5V/2.4A, 9V/2A, 15V/1.5A for each ports.
More fancy images
Let’s do the test, I will use a usb detector to monitor the charger voltage and ampere, this detector can monitor up to 9V/5A, and I will use my Zenfone 2 to test this charger which can charge maximum at 9V/2A so I think the detector will survive.
More fancy images
I will charge my phone from 10% to 100%, and monitor via Asus stopwatch app, as for new software update, Asus has changed how fast charge works, they will limit the ampere to 0.83A when the screen is on, and can only charge at maximum when the screen is off.
It took about 1 hour and 45 minutes to completely charged Zenfone from 10% to 100%, the phone itself would limit the ampere to 0.35A when it reached 90% so we could charge faster with full ampere.
So here are some pictures of the test.
Let's get started.
The phone is increasing the ampere when the screen is off.
It took 6 mins to charged 16%.
10 minutes to 22%.
23 minutes to 39%.
35 minutes to 52%.
54 minutes to 75%.
From this time, my phone was limited the ampere to normal charging, which took more time to fully charged. It took 1 hour 25 minutes to reach 93%.
1 hours 30 minutes to reach 96%.
And finally, the phone phone was fully charged in 1 hour and 45 minutes.
Conclusion
This is a great fast charger with a great build quality, solid USB cable for long time usage, build-in 2 quick charge 2.0 ports so you can charge 2 devices at the same time.
The only disadvantage from the charger is the temperature when you charge 2 devices at the same time, it’s really hot, I don’t have any device to monitor the temperature, but it was very hot when I touch the charger.
For the price of $21.99 USD, this is the best charger in its price range and a good alternative for original Asus BoostMaster charger which costs about $29.99 USD. You can buy this charger at.

Hello, I just want to know whether this charger is backwards compatible. Means if I have phone with no quick charge, 5v 2A input will it work..??
Regards

I'm more interested in that voltage ampere indicator/detector
Where can I buy that?

Tronsmart Presto: The new 12000 mAh Quick charge 3.0 powerbank

Our new smartphone is more powerful everyday, but we just can’t put a big battery in a small and slim device, so they invented PowerBank.
Tronsmart is one of the first manufacturer to introduce Quick charge 3.0 PowerBank, they named it “Presto”, it’s powered by 12000 mAh battery which can charge up to 4 times for our Zenfone 2. Sadly, this powe rbank supports QC 3.0 but our device can only charge with QC 2.0.
Tronsmart Presto Specifications:
Qualcomm Quick Charge 3.0: Up to 4x faster than standard chargers, able to charge compatible devices to 80% in just 35 minutes. Backwards compatible with all versions of Qualcomm Quick Charge.
Type-C Input and Output: Use it to quickly recharge the 12000mah external battery, or to power your Nexus 6p/5x with USB-C/Type-C ports.
Remarkably Compact: Much smaller than other high-capacity portable chargers. No other charger packs this many recharges at such high speed into such a small space.
Stylish, Practical & Safe: Smooth ebony varnish with 4-LED battery level indicator, 100% safe circuit protection; charger automatically shuts down if short circuit or overload occurs to protect your devices.
You can check out more information and the price at: https://www.amazon.com/Tronsmart-Pr...d=1466731576&sr=8-3&keywords=tronsmart+presto
What You Get in the box: Tronsmart Quick Charge 3.0 12000mAh power bank, 30cm USB-C to USB-A cable, welcome guide, our worry-free 18-month warranty and friendly customer service.

2. Tronsmart Presto Power Bank:
The power bank is made from all plastic, with black color and solid build. I really like this over Xiaomi Power Bank because the Mi Powerbank is easy to get dirty as there is a lot of dust in my place.
On the front of the Tronsmart Presto power bank, you will see a Tronsmart logo and 4 stylist battery level indicator white LED.​
On the back, you will see some technical informations about the output and input of the power bank. Here is a closer look:​
On the top, there are two port, the USB 3.0 port is for output only, but the USB-C port you can use it for both output and input (to charge your devices or to charge your powerbank).
The power bank comes with one 30cm length USB-C and USB 3.0 cable, the cable is solid too.​
On the side, you can find the power button, you have to put it to power on the Tronsmart Presto before use (not like Mi Powerbank, you just put the device in and it will automatic charge your device!).
3. Charging Zenfone 2 with Tronsmart Presto.
I’m using Zenfone 2 with Anker cable to test Tronsmart Presto power because Zenfone 2 doesn’t support USB-C.​
I started charge the device from 3%, and it took 10 minutes to charge from 3% to 17%.​
I got 20% in 13 minutes. There is not much heat as QC 2.0 charger.​
I got 41% in 29 minutes.
​
I got 58% in 42 minutes.​
I got 79% in 1 hours and 2 minutes, the phone is now charging at normal mode to extend the battery life.​
I got 89% in 1 hours and 16 minutes.​
The phone is now fully charged at 1 hours and 48 minutes.​
4. Summary
Pros
Solid build.
One of the first QC 3.0 compatible power bank for fastest charging speed.
Not much heat generated while charging.
Cons
Not much accessories.
A bit boring design.

Thanks for the review!
