    Bacon got a reaction from Tt Tautlih in What kind of holder product would you like to see in 2015?   
    Made some sketches with different types of clamps for a general impression of the idea:

     
    The holder would be clamped onto the edge of a desk (or shelf) as pointed out in the bottom part of the image.
    And the rotation of part A allows it to be clamped vertically too.
     
    I hope the image/explanation is clear enough.

    The Smart Clip arrived two days ago!


    Inside the box is the Smart Clip itself and a quick start guide


    I decided to test it out on my desk first and I noticed that the sticky suction was very sticky, I had to use a lot of force to remove it from my desk   
    It will accumulate some dust over time, but as described in the product page, it's really easy to rub it off with some water.


    The (gray) rubber grips work really well to hold my iPhone 4 in place with and without a case. However, my LG G2 is wearing a very thick case (about 17mm thick) and the grips are too small to hold the phone. But it works just fine when the case is removed.


    Time to take it out for a ride! I tried to mount it on my dashboard but after a few minutes the suction slowly came loose. I guess it doesn't really like my dashboard surface material/curves.   


    Oh well, I'll just place it on my windscreen!


    It feels like its glued onto my windscreen and holds up really well. My phone didn't budge at all during my car ride in the city (with the usual braking, accelerating, sharp turns, speed bumps etc).


    I'm really loving it so far and it sure makes navigating a lot easier

    Bacon reacted to Tt Tautlih in [Tips & Tutorials] How to Choose a Portable Power Bank   
    What is a Portable Battery Pack?

    Portable battery packs are a form of mobile power supply that provides convenient mobile charging for smartphones, phablets, tablets and other 3C accessories. They are multipurpose, small in size, safe, reliable and long in life.
     

     
    Mobile Battery Pack: Basics

    Basic components of a portable battery pack comprise of the following: battery, circuit board, USB output, micro USB input, power switch and LED indicator. The battery cell is discharged via the Micro-USB output and USB output.
     

     
    Battery Cell Types 
Li-ion (Lithium-ion) : 

    Regular (18650) lithium cells are characterized by uniform size (Diameter: 18mm, Height: 65mm) Single battery holds an average 2200~2600mAh and are mainly manufactured in Japan/Korean/China. Grade A lithium cell batteries holds an average 3000~3400mAh but are mainly manufactured in Japan and Korean for their respective markets only. Li-ion cells have high energy densities and costs less than Li-Polymer due to cheaper and quicker production methods.
     

     
    Li-Polymer :
    Battery has high plasticity that resembles a plastic film and therefore can be adapted to match a variety of packaging shapes and sizes. They do not have a uniform size like lithium ion cells. They also have a greater life cycle degradation rate than Li-ion and is around 20% lighter. Due to high costs, majority is produced in Mainland China. Apple’s iPhones and iPads use li-polymer to match their slim designs.
     

     
    Power Conversion & Efficiency Calculated

    Mobile power supply capacity is directly related to battery capacity of mobile device. Assume you have a 5000mAh battery pack to charge an iPhone 5 (1440mAh). Using the mathematical sum of 5000/1440 to identify how many times a device can be charged, figures indicate it can be charged 3.47 times, but the actual use is 2.36 times. Why is this? 

The reason for this is because the battery cell voltage is 3.7 - 4.2V, whilst the mobile device is charged at 5V. This results in power transfer loss. 


     
    Battery capacity conversion calculations:

    ♦ Mobile power capacity x Product conversion efficiency (75~90%) = Actual discharge of capacity

    ♦ Actual discharge capacity x Conversion efficiency (85~90%) = actual charge capacity into apparatus

    ♦ Actual charge capacity / unit build battery capacity = actual charging time
     

     
    Power Bank Charging Times 

    Power bank charging times will vary with the external power supply used. For instance, the majority of desktop and laptops use a USB2.0 (5V/500mAh) or USB3.0 (5V/900mAh) output, whilst a standard wall charger may use a (5V/1A) or (5V/2A) output. In these examples, the (5V/2A) output will charge fastest.
    Action under 5000mAh Power as an example:

    ♦ 5000mAh / 500mAh (USB2.0) / 0.85(Energy conversion efficiency) = 11.76 hours

    ♦ 5000mAh / 900mAh (USB3.0) / 0.85 = 6.53 hours

    ♦ 5000mAh / 1000mAh (AC) / 0.85 = 5.88 hours

    ♦ 5000mAh / 2000mAh (AC) / 0.85 = 2.94 hours

    *Above is based on theoretical calculations as due to battery energy losses
     
    Things to watch out for :

    1. Large capacity and cheap price - Price reflects quality, therefore battery packs claiming to have a high capacity but much cheaper than a battery pack with lower capacity is something users need to be cautious of.

    2. High capacity and low weight - Battery capacity is proportional to weight.

    3. Small size and high capacity - Volume is proportional to battery capacity.

    4. Warranty period less than 1 year - Possibility of recycled batteries used.

    5. No battery certifications - No third party certification-licensing unit provided therefore users will have no idea how safe the device really is.
     
    How to properly use your mobile battery pack:
     
    1. Do not charge and discharge your battery pack at the same time as it may cause abnormal operation that may result in damage.
    2. Do not place in hot areas or fire as it may result in the battery exploding.
    3. Do not use in areas of high humidity as battery it may cause rust or short-circuit the boards

    4. Do not place near children.
     
    What is MFI Apple Certification?
    Apple MFI Certification (see logo: right) represents a label that is printed on product packaging. 

This certification is given upon passing Apple’s technical approval with a device having a 30 pin, or 8 pin connector and to ensure a device is fully compatible with Apple products. A certain amount of royalty is paid to apple for this certification therefore products under this specification are usually priced higher. This however does not guarantee that manufacturers will not use inferior grade products or false battery capacities in their production. Increasingly worrying is the amount of products that have not been certified yet have the apple MFI certified logo.
     

     
    Flight Safety Regulations

    According to flight safety regulations, any charging equipment (spare or installed power should be clearly labeled in (watts) and must not exceed 43,200mAh. To calculate this:
     

     
    WH(Wh) that is the power unit with the formula :
    P(powerWH)=V(voltageV) x I(capacity mAh)/1000 
Using LUXA2’s P-MEGA 41,600mAh Power Station as an example:
(41,600mAh / 1000) x3.7V = 41.6A x 3.7V =153.92Wh .Can be placed in hand luggage
160Wh / 3.7V = 43,200mAh = maximum allowed to be carried on plane
     
    Other Relevant Information :
    1. Korean batteries (Samsung, LG) with single cell of 2200mAh (Li-ion) costs around $2. Therefore a 18000mAh battery pack core battery possesses around 8 batteries ($16), plus electronics components, housing, labour costs, shipping, vendor costs and channel profits may be sold to consumers at $15-20? This is of course no possible as a more reasonable product pricing range should be around $35-40.
     
    2. A standard 2200~2600mAh Li-ion battery weighs around 45-46g plus electronic components and case should therefore weigh around 70g. On some Internet sites there are some high capacity battery packs 18000mAh that weigh only around 380-400g. This is not possible.

    Well, I am planning to replace the iPhone 4, but there are so many good phones out there (and coming out soon) I can't decide yet which one to choose

    Bacon got a reaction from Tt Andy in Do you install your PSU facing up or down? whats your choice?   
    Facing down, since there's a dust filter down there. Also I tend to drop some screws when installing new hardware and I wouldn't want them to fall into the PSU.
