These 5200mAh charge bricks can get pretty expensive. I’ve seen them around for $99, the incase 2500mAh power brick at Apple store is currently selling for $49.

The thing to remember about power bricks is the power comparison to what you are charging. The ipad rechargeable battery is 11,560mAh while the iphone 5s is 1,570mAh. In our testing we found the PQI will save our ipad from crashing in the middle of the day but don’t expect a full charge or multiple charges.

However, with the iphone 5S we could charge 4 times on a single full charge. The blue power meter LED on the face of the PQI has 4 LEDS to indicate the charge level. 4 LED lights usually does mean 4 full charges.

We liked it so much we have been using it for months now and we are so happy to recommend it we are giving it away FREE to anyone who joins our exclusive email list and book a support or repair call to the end of March (2015).

Computers attract dust because of the negative air pressure, fan systems and no filters in your average generic computer case. The examples in the pictures might look like computers that are 6 or 7 years years old, but both are generic systems,  less than 2 years old and suffered hardware and hard drive failures as a result of dust.

Dust affects a computer in various ways:

•  The dust creates a blanket or insulating layer that makes computers run at elevated temps – running at high temps reduces lifespan by up to 70% especially in workshops and factory settings
• dust creates ESD (electro static discharge). We see many computers with dust build up every year that did not survive a power surge.
• dust makes the computer fans noisy and ineffective to keep temps down and maintain air flow

A computer with no build consideration for dust is a problem for offices everywhere, worse in workshop settings and can be very uneconomical because hardware or computers need replacing too often or short of expected life span. However, the two computer interiors in the image above are from home offices in the suburbs. Cleaning dust from a computer using canned air is not advised because most types of canned air are not air, but chemicals that create air pressure which in our experience can also be hazardous to the frail electronics of computers if turned on an angle. Vacuum cleaners are probably the least effective way to clean dust in a computer.

Minimizing dust build up in computers.

In heavy dust prone areas dust safes are available that are expensive, imported hardware. But for small home based business, workshops and trade shops dust can be minimised with the concept of positive air pressure. This is possible with small tower PC’s (laptops are more prone to dusty demise and cannot be cleaned easily).

Using a particular type of case with modified fan systems and dust filters we are able to significantly reduce dust build up. The dust filters are very easily removed for cleaning every 6 months or so. The cases (chassis) are small (mid towers)  and light and cost no more than our custom build model with SSD advertised on our new computers page.
