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 2000-4000mAh capacity. More powerful devices such as iPad / Tablets are normally between 6000-10000mAh. You can usually find the battery capacity (mAh) ratings on your various devices, in the product manual / documentation.

For example the iPhone 12 has a 2815mAh battery, so divided up with a 10000mAh Power Bank, will theoretically give you 3,55 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 being 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 good 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's 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 10000mAh. How will you confirm you've got the listed capacity?

PowerBanks from Chill use handpicked A-Grade cells from renowned battery cell manufacturers. Secondly all models are equipped with energy-optimized micro-chip control and safety. So Chill's 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 Chill's PowerBanks support my devices?

Chill's PowerBanks 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 Power Bank instead.

The PowerBank itself is also being recharged via 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 decent 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 experience 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 also on the operating conditions.

Cheap / standard Power Bank also have cheaper cells inside, and usually the capacity will drop rapidly after just a few months.

Better Power Banks are designed to theoretically deliver 300-500 charges / cycles and will typically still have +50% capacity remaining after this. Depending on the use and conditions a lifespan of 1-3 years is usually to be expected - however this is also a huge interval!

Operating conditions have a crucial effect on battery cells lifespan, 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 fully depleted state (if not used often, it is best stored at ~50% capacity)
- 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)

Can I bring a Powerbank on airplanes?

Yes! Most airlines allow to bring 1-2 Powerbanks under 100Wh (<27.000mAh) as carry-on hand luggage. Higher capacity Powerbanks usually require special permission from the airline. Powerbanks are usually not allowed in the checked in luggage.

USB Charger FAQ

How powerful USB charger should I use with my equipment?

It's always the connected USB devices which control how much power it will draw from a USB charger - not the other way around. So you can not buy a too powerful USB charger, thus damaging the equipment.

The more powerful USB charger, the more power the attached devices will also be able to draw, and thus obtain the potentially fastest charging time.

If a USB device is designed for maximum Max 1A input, it will not be able to draw more than this, just because you connect it to 2A based USB charger instead. However, there are big differences in quality of USB chargers (and cables), so by using a better / stronger USB charger you wil ensure it actually also have enough power available. Secondly the conversion efficiency is also typically better, in better/stronger chargers, so it will overall also lower the electricity bill.

Many standard / cheaper USB chargers specified for example with 1A/2A Output will in real life only be able to deliver 70-80% of this. So by using a stronger quality USB charger instead (eg. With 2.4A/3.4A output), the attached devices will thus able to draw it's full potiential, and thereby actually charge 20-30% faster.

What is Smart IQ (Auto Detection)?

Apple products do not follow the regular USB standard and therefore USB chargers typically needs to be optimized for either Apple products or others, like Android. This limits the functionality significantly.

Secondly some USB Chargers / Powerbanks har multiple ports with different output ratings (ex. 1A and 2A)

With Smart-IQ Auto Detection the connected devices will be automatically detected as Apple or Non-Apple, and thus all USB devices will have full functionality on any available USB ports.

My Apple device say "not charging" when I use it with non-Apple chargers?

It is normal for Apple products depending on model, IOS version, cable etc. to say "not charging" when non-Apple chargers / cables / power bank etc. are detected. Apple primarily want you to use their own products only. However they should still be able to be charged!

Does charging time differ?

It is always the connected devices that control how much power they draw from a USB charger - NOT the charger that controls how much power delivered to the device.

One should actually just make sure that the USB charger has enough available power (Ampere output) for the connected device(s). If a USB charger can not actually deliver the needed power, the charging will thus also take longer.

In addition, cable length and quality also affect results. It is NOT given that USB cables can deliver the full potentiall needed by the attached device.

No products will draw their maximum input power during a full charging cycle. This fluctuates with the battery capacity (typically only high power between the 30-70% battery), cable quality and length, temperature / air humidity and other conditions they might be designed for.

So charging time can vary according to the conditions. Typically mainly fluctuates based on remaining battery capacity and cable used (if you use different cables, you might notice different results). Last but not least, many cheap / no-name USB chargers are not able to deliver their specified output ratings.

When should I consider a USB-PD (Power Delivery) and/or Quick Charge capable USB charger?

Your equipment should be decidedly USB Power Delivery (USB-PD) and/or Qualcomm Quick Charge compliant to charge faster on a USB-C PD and/or a Quick Charge chargers. Check your documentation on your various devices (Many newer hi-end Smartphones and tablets etc. has a USB-C connection, however this does not necessarily mean they also support USB Power Delivery. iPhone 8 and ahead support USB PD.

A Quick Charge USB and/or USB PD capable charger can also charge ordinary - non QC/USB-PD compatible - USB devices, but at lower (regular) speed.

Why should I buy a USB charger from Chill?

USB chargers are available in many grades and price points. It is basically not products which people care much about, despite typically used daily. Therefore, most USB chargers are made with a focus on price, and that means they typically compromise on performance, conversion efficiency and safety features.

All USB chargers from Chill focus on performance / ratings and ultra high conversion efficiency (which lower the energy bill), as well as extended safety and functionality.

If you use a USB charger daily, then a decent USB Charger from Chill / Deltaco could quickly pay for itself, due to electricity savings. They all offer a higher conversion efficiency compared to most original / cheap / no-name USB chargers.

USB chargers are basically cheap to produce, so we think it is simply foolish to cut corners just to save a few bucks. The price difference between a cheap / poor USB charger and a high-quality real rated USB charger with good safety is minimal.

So stick to branded USB chargers from reputable sellers and always avoid USB Chargers and Powerbanks from Asia platforms (most are fake specs and fake CE rated with poor safety to keep price down)

What about cheap USB chargers from foreign trading platforms?

The cheap USB chargers you often find on foreign / Chinese trading platforms have basically two problems:

1. The output rating (ampere) is not credible. They often can not deliver the promised output continuously.
2. The safety is questionable, as this represents a large part of production costs. Often they are fake CE / FCC marked. It is expensive and difficult to meet CE safety regulations, which is required in EU. You can be pretty sure they do not spend these money on a cheap USB charger - but it is very cheap to just print the CE mark.

Besides the increased risk for short circuit, fire and shock it also affect the attached equipment. Cheap/poor USB chargers usually also have a lot of electronic noise/fluctuations (Ripple), which will cause unnecessary wear and tear on the devices and batteries.

In general USB Chargers are inexpensive, so don't cut corners on safety. Stick with reputable EU based brands/sellers like Chill to ensure higher quality and safety.

Meget lækker powerbank i både design og ydelse!
Har også en anden dyere 20.000mAh Powerbank, som ikke engang kan levere lige så meget power som denne her, så ganske imponerende. Desuden lader denne mit udstyr markant hurtigere op også.
Så dog gerne der også fulgte en USB oplader med, så man ikke skulle bruge den til sin telefon.
