Sony Power Bank CP- F10L Review Battery Pack

Hi, this is a review of the Sony 10,000 mAh Power Bank - model CP-F10L

The power bank uses Li- Polymer cells two of them 5000 mAh each, for those who are unaware there are two types of batteries usually used Li-Ion and Li- Ion Polymer also called as Li-polymer..

The later is more energy efficient and light weight but is costlier than Li-ion batteries.
The real capacity of this cell is about 67 % i.e. 6700 mAh - this loss is due to factors like "Voltage Conversions", "circuit resistance" and other variable factors.





It supports simultaneous charging of two devices with maximum 3.6 Ampere, so each port can easily output more than 1.5 Ampere.

If you’re not sure what this means - take a look at your native phone charger, it will have an Ampere rating ... let’s say it says 1.5 Ampere... 
So as long as the power bank supports 1.5 A the charge time would almost be the same.... if the power bank can change at an higher ampere that the phone charger eg 2.0 A - the charge time would be reduced.
Conversely if the power bank has an Ampere rating that’s less than the native charger, the device would take a long time to charge or in some cases not charge at all.

This power bank can be charged using a regular DC 5.0 V charger or the USB interface of the computer.

I performed some tests using my Sony phone.

It took about 6 hrs and 45 minutes to completely charge the Power bank using a Sony phone charger @ 1.5 Ampere .   

The power bank charged my Phone 1900 mAh battery in 1 hour 18 mins which was faster than my
native 1.5 Ampere charger.. possibly because it used an higher Ampere to charge it ...

The Standby time is more than 3 days after using it to charge the 1900 mAh battery twice...

It has Smart Led Indicators...... saves a lot of battery by avoiding flashy Displays.

And has certain safety measures like - Overcharge protection / Abnormal temperature detection - optimal
working temp. is between 10-30 degrees Celsius.

There are 2 LED's Green and Orange.

Orange
While charging the Orange light will glow... once the charge is completed it will stop glowing.... if it constantly blinks there’s a malfunction...

To check remaining power
Press the power button and observe the Orange light.
Flashes 3 times *2 battery full
Flashes 2 times *2 medium battery
Flashed 1 time * 2 low battery
No Flash empty battery.

Green-

While the power pack is being used to charge a device.
Constant green Glow battery full
Green led flashes slowly - low battery.
Green led flashes rapidly - malfunction.

Fake alert...
There are lot of fake power banks being sold , mainly on sites like ebay - the best way to spot one, is the price vs the battery capacity ,which is usually very cheap, other factors would be the packaging, weight etc.. 
A 10,000 mAh battery will definitely have a good weight to it, this one weighs 260 grams and it has an aluminium body.

Hexamine Portable Travel Stove

The Hexamine stove is portable and a great travel companion, it uses Hexamine Fuel Cakes also called as Esbit.

These cakes are supposed to be smokeless, odorless, should not liquidize or leave ashes behind.

I experimented with 1 of the 2 free Hexamine fuel cakes i got with the stove and even though it was smokeless and odorless while it was burning, as soon as i suffocated the fire, it gave out a nasty smell and it left sort of an ash mound......

Efficiency wise it took about  8-9 minutes to boil 350 ml of water and it was reduced to about 75 % of it's original size. The total time it's supposed to last is about 15 minutes with a flame temperature of 600 Degree C.




After some amount of research i found Yellow haxamine cakes from Flem-O which are supposed to be superior and each cake is supposed to last about 2 hours... yea that's what it says.. will put it to the test soon...

There are a lot of other alternatives like butane canisters, Alcohol or wood burning stoves.... but nothing comes close to the value for money and portability that the Hexamine stove offers.

Stove cost - 125 - 200 Rs. approx
Flem O -Hexamine Cubes 12 Rs. each approx

I will be using this stove shortly in high altitudes where the efficiency will suffer, if time permits i will post another video on how it handled itself.

If you intend to use this setup, as a Safety precaution one needs to use the stove out in the open and not in enclosed areas.... since Hexamine produces Toxic gases when lit.... which can cause serious harm in some situations... symptoms of poisoning would include but not limited to nausea, vomiting and kidney failure.

Aces High Guitar Solo - Iron Maiden


Live to fly,fly to live. Aces High. I can play the solo. But I could never sing this one LoL !!! 



Aces High -  Iron Maiden 


There goes the siren that warns of the air raid
Then comes the sound of the guns sending flak
Out for the scramble we've got to get airborne
Got to get up for the coming attack.

Jump in the cockpit and start up the engines
Remove all the wheelblocks there's no time to waste
Gathering speed as we head down the runway
Gotta get airborne before it's too late.

Running, scrambling, flying
Rolling, turning, diving, going in again.
Running, scrambling, flying
Rolling, turning, diving.
Run, live to fly, fly to live, do or die
Run, live to fly, fly to live. Aces high.

Move in to fire at the mainstream of bombers
Let off a sharp burst and then turn away
Roll over, spin round and come in behind them
Move to their blindsides and firing again.

Bandits at 8 O'clock move in behind us
Ten ME-109's out of the sun
Ascending and turning our spitfires to face them
Heading straight for them I press down my guns

Rolling, turning, diving
Rolling, turning, diving, going in again
Run, live to fly, fly to live, do or die
Run, live to fly, fly to live, 
Aces high.

Bottle Cap Camera Mount

Bottle Cap Tripod



As the name suggest this is used as a Tripod to mount the camera, its not as flexible as a small tripod -

being restricted to about 10 to 15 degrees.... but it definitely gets the job done.

It's compact and extremely handy while travelling and in situations when you need to take those slow
shutter speed - long exposure shots and of-course Selfies ...

It easily fits over most standard bottle caps, one needs to use a little common sense.
Mounting it over a small or light weight bottle could result in damaging the camera.

Overall all its a nice addition to ones camera accessory bag.
