A-Grade Lithium-Ion Battery Cells inside

The Chill PB-4800 USB Power Bank is equipped with selected SAMSUNG / LG / BAK A-Grade Lithium-Ion cells inside in order to provide market leading performance, durability and quality.

The battery cells are the most important components in a Battery Pack, but also the most expensive parts.

So unfortunately many makers choose to use cheap 2nd hand cells, 2nd sorting cells, outdated formula designs and even fake rate the mAh capacity in order to sell cheaper.

Intelligent Power Management IC

The intelligent 'Power Management' IC make sure you get the most out of your Chill Power Bank as posible!

It offers a very high conversion efficiency (~90%), so as little power as possible is consumed during the transfer process into your various devices.

it has a Full Protection Circuit so your Chill PowerBank can remain reliable in all kinds of working conditions.

Smart LEDs will show battery status 

The Chill PB-4800 USB PowerBank is equipped with Smart LEDs which conveniently show you the estimated battery capacity left and charging status.

An Auto Power Off feature will automatically turn off the PowerBank itself when there is no attached devices being detected.

It has very low self-discharge, so battery cells do not deplete easily when not in use. This is a major issue with low quality Power Banks, as they cannot maintain its capacity inside very long.

USB Cable with changeable tips

The Chill PB-4800 Power Bank comes with a convenient USB cable with changeable tips/adaptersfor easy charging your various portable devices and the PowerBank itself.

Standard included are Apple 30-pin, Nokia, Micro-USB and Mini-USB tips. Additional tips/adapters are can be purchased seperately if needed. You can also use your regular USB charging cables.

The PowerBank can be charged from any USB-port, but it is faster with a USB Power Supply (5A/2A max).

Which Power Bank capacity (mAh) should I choose?
The Capacity (mAh) is also related to the size and weight of the Power Bank, so bigger capcacity also means bigger size and weight.

How many times you can charge your devices depends partly of the PowerBank capacity (mAh), set against the battery capacity (mAh) of the devices you want to charge. Smartphone batteries typically have between 1300-2500mAh capacity. More powerful devices such as iPad / Tablets are normally between 6000-12000mAh. You can usually find the battery capacity (mAh) ratings on your various devices, in the manual / manufacturer documentation.

For example the iPhone 5 has a 1440mAh battery, so divided up with a 12000mAh Power Bank, will theoretically give you 8 full recharges.

However it also consumes energy to actually transfer / convert the power - both in the Power Bank and the recipient device. Secondly, there is also a natural loss in the cables and factors such as temperature, humidity, and not least wear on both ends come in to play.

In other words, you can not just divide the PowerBank capacity with the devices battery capacity. A rule of thumb says that about 20% goes to the above.

Finally, one should also remember that if the device is ON while beeing charged, it also means up to double power consumption. In this case the Power Bank both have to charge the battery and keep the device operated at the same time.

A cheap / inferior / standard Power Bank will typically have a significantly poorer energy efficiency than a Chill Power Bank. Secondly fake rated PowerBanks are very common in the market.  All Chill Power Bank is specified with real capacity indication.

I tried a Power Bank in a different brand with fairly poor performance. Is Chill any different / better?
The two most expensive parts in a Power Bank is the battery cells and the Microchip (optimization and safety). The battery cells constitute up to 80% of the production cost. If a manufacturer will sell cheap power bank, then it is here to save!

So the majority of cheap standard Power Bank on the market are therefore either equipped with cheap battery cells, poor security / energy optimization and / or even with fake rated capacity (mAh). It's incredibly easy for a manufacturer to make a nice design, put 5000-8000mAh cheap / low cells in it, and indicate and sell it as 10000-12000mAh. How will you confirm you've got the listed capacity?

Chill PowerBanks only use handpicked premium A-Grade cells from highly renowned battery cell manufacturers (Samsung, LG, BAK, TCP, Sanyo, Panasonic etc.). Secondly ALL models ar equipped with energy-optimized micro-chip control and safety. So the Chill Power Banks have virtually no self-discharge and will retain its capacity much longer. 

Obviously they might cost a bit extra, but it pays off. You get a much better price vs performance ratio - like with other energy A rated appliances.

Will the Chill PowerBanks support my devices?
Chill PowerBank works with all equipment capable og being charged via USB. Virtually all modern Smartphones and iPad / Tablets, cameras, GPS devices, Bluetooth devices etc. is using one of the various USB connectors for charging. If you already use a USB charger / power supply with your devices, then you can also fit your regular USB cable in the Chill Power Bank instead.

The PowerBank itself is also beeing recharged via USB (micro-USB). Just connect it to your ordinary USB charger / power supply which came included with your Smarthpone / Tablet, a USB port in your computer or any other USB charging source / power supply (sold separately).

The capacity estimation seems a bit inaccurate?
The capacity calculation in a Power Bank works by measuring the internal battery voltage (high capacity = higher voltage and vice versa).

So for optimal capacity usage, the electronics need to know the battery cells current full and empty levels. This is normally measured continuously during full charge/discharge cycles (Full cycles are not required for daily use with a Chill Powerbank)

For the same reason, maximum capacity usage is only achieved after 3-5 full cycles when new! Also Actual capacity is gradually affected over time when used etc.

If you expericence the capacity estimation seem a bit imprecise, it is basically just a matter of during a full cycle for calibration. You can follow this approach:

Manual Calibration:
- Discharge the Power Bank completely
- Fully recharge the Power Bank (until LED / LCD Display does not blink)
- Disconnect the charging cable for a few seconds and reconnect it to charge again. After a moment the LED / LCD will again be fully lit

The Power Bank is now calibrated and can be used normally again.

How long is the lifespan of a Power Bank?
A Power Bank is basically a Li-ion or Li-Polymer based battery wrapped in electronics, which then enables use via USB standard.

The lifespan of the batteries themselves depends largely on the cell quality, but alsoon the operating conditions.

Cheap / standard Power Bank also have cheaper cells inside, and then the lifespan can vary from a few months to 1-2 years. Does it have reasonable battery cells, they should be able to cope with 200-300 charge / cycles).

Better Power Banks, like Chill Innovation, are designed to deliver more than 500 charge / cycles and will typically still have 50-85% capacity remaining after this. Depending on the use and conditions a lifespan of 2-5 years is then to be expected.

Operating conditions have a crucial effect on the lifespan though, so you must follow these guidelines to maximize the life:

- Use the USB Power Bank regularly! Minimum one full cycle every 3 months is recommended*
- Never store your USB Power Bank in a depleted state.
- Do not use your USB Power Bank in very high humidity and heat / direct sunlight conditions.

(*Cheaper / inferior Power Bank typically requires to be used more often)

Good Quality

Bought it during a stay in Denmark, as my iPhone kept running low on power.
What a brilliant product, which actually works and in a very handy design. After half a year, I still use it regularly with no problems. A travel pouch or something would have been a nice option though, as the acrylic tend to get scratched over time.

Fuldt tilfreds!

Virker markant bedre end den jeg købte på Dealhunter til trods for den havde højere angivet kapacitet. Og så føles den altså også bare bedre i alu, så er fuldt tilfreds :-)
