A 20000mAh power bank isn’t the cheapest thing out there, but the TOPK I2009Q not only offers that capacity at an affordable price. It also includes an 18W QC 3.0, making it one of the best deals you can get when buying a power bank.
This power bank features four ports, two USB-A for output, a micro-USB port for input, and a USB-C port for output and input. Although the micro-USB port might seem a bit archaic, it's great that it's an option for people who haven’t fully adopted the USB-C lifestyle.
In addition, the two-tone design of the power bank feels great in the hand, though the overall weight is a bit hefty, even for a 20000mAh capacity.
For the people who have multiple devices, it can get a bit cumbersome trying to carry three different cables for each of your devices. But with the Pineng PN857, you wouldn’t have to! Whether it’s Apple’s Lightning port, USB-C, or even micro-USB, the Pineng power bank has got you covered.
The 10000mAh battery is equipped with three charging cables for whatever modern device you need to juice up, whether it’s an iPhone, Samsung, or even something a bit older. There’s even a spare USB-A port if the connection you want isn’t on there.
Unfortunately, the device isn’t capable of using all three connections at once, and it doesn’t have any quick charging feature so expect slower charging times. There’s also the fact that the power bank only charges with micro-USB, which can be a huge minus for certain users.
How do power banks work?
A power bank lets you deposit electrical energy into it to be used for later when needed.
These batteries are designed with a special circuit to control power flow into your devices.
The special circuit ensures that the right amount of power goes into your devices, and stops when your devices are fully charged.
This way, your devices will not overcharge and cause a short circuit to happen.
How long do power banks last?
Assuming that you use them almost every other day, a power bank should last you between 1 to 2 years in mint condition. Its wear will certainly show once into a year of regular use. Still, these power banks won't be very unusable.
User experiences will vary, such as the ports being loose for your cables to plug-in.
This will affect charging your devices efficiently especially if you're one to just toss the power bank charging your device into your bag at freewill (without a storage compartment to restrict movement).
At the same time, as with most tech uses, charges won't be as full as they used to be.
You'll find that the power bank's capacity may be cut to as little as a quarter or even half the usual.
This is due to the chemical reaction in rechargeable batteries, whereby the more charging cycle it goes through, the more "crystals" it forms inside.
That actually leads to less efficiency in holding more charge (and passing into your device).
Is using a power bank bad for your phone?
You may have heard of the rule to not use your phone (or any other devices) when it's charging. This is because when electricity flows into your device, heat is generated naturally. And when you use your phone, heat is also...generated.
By using your phone while it's charging, it'll cause even more heat to generate in your phone and thus, the action will risk frying your phone or even yourself.
In short, it's like asking for your phone to be fried slowly.
Even if today's phones are made with more heat-resistant materials, they are still prone to burns that can potentially cause a fire.
Plus, today most power banks come with overcharging protection features.
Can you charge power banks overnight?
Back then, we would say no. However, with today's advanced technology, you can.
The simple answer is that because today's power banks (and phones) are commonly built with smart protection in the form of "trickle charge".
It works such as the device will self-discharge once the battery's capacity is full.
This charging protection feature is also couple with extra support such as high-heat resistant materials.
How do I choose a power bank for my phone?
There are a couple of things to remember when selecting a power bank:
1. Number of charging ports
See what is the number of output ports on the power bank.
This is useful for if you have more than one device to charge, so that 2 ports would be ideal in that case.
2. How many volts (output voltage number)?
Check what is the output voltage number that a power bank can give.
Today, to charge most devices, it's recommended to get a charger with a power output of at least 2.4V for standard charging time.
If the power bank can only output less than that (like 1V), it will result in slower charging speed than usual.
To easily determine this, get one that matches your phone charger's voltage output.
3. Charging technology
Special technology supported by power banks.
For example, if both your power bank and the smartphone supports Qualcomm Rapid Charge, you can charge faster than how much output power your smartphone normally needs.
You should also consider a power bank with auto-discharge to stop sending power to your device once it detects that the latter is fully charged.
4. Milliamp-hour (mAh)
Check how much milliamp-hour (mAh) the power bank can hold.
From here, also expect that there will be some power delivery loss which depends on the quality and length of the charging so cable.
At standard, only expect about 80% power delivery (see next point).
That means 20% of the power in the bank will not deliver into your device.
Power bank capacity x 0.8 (80% of delivery), divided by device's battery capacity = charging times (approximately)
Example: A power bank with 10,000 mAh can charge a phone with 3,000 mAh for 2.6 times (10000 x 0.8/3000 = 2.6)
Tips to charging faster?
Here's an insider tip from us: charge with a shorter (and high quality) cable!
This is because the longer the cable, the more power is lost during the power transfer to your device.
In short, charging cables have electrical resistance on them, and the longer they are, the more resistance!
