Modern gadgets have amazing capabilities, but all the "magic" instantly disappears if a smartphone or other high-tech device is disconnected due to a dead battery.
If such a nuisance occurred at home, it is enough to connect to the charger to fully restore the device. In the car, the phone can also be charged using a special adapter.
Being in nature or traveling by public transport, such an opportunity is absent, but it is enough to have a small portable battery with you, so as not to worry about the possibility of charging a mobile device anywhere.
This article will describe in detail about the main technical parameters that you should pay attention to when choosing a bank for a smartphone.

What to look for when choosing a bank
When choosing a new Power Bank, you should pay attention to many characteristics, despite the relatively simple design of such a device.
Capacity
The stock of electricity that a bank can accumulate is the main characteristic of such devices. Choosing a product by capacity value is quite simple: the more the better. It should only be remembered that products with the possibility of accumulating a large amount of electricity will have large dimensions and weight.
The value of the capacity will also depend on the gadget that you plan to charge using a portable battery. A small Android phone will require significantly less power to fully charge than an iPhone or tablet.
The number of charge cycles of the gadget from an external battery is also very important. Going on a hike or fishing for a few days, you should stock up on a powerful device to recharge the phone.
Amperage
With the same capacity, banks can give electricity of various capacities. The charging speed of the smartphone depends on the value of the current, so if there is no way to keep the gadget on charge for a long time, then you should choose a portable battery with the maximum value for this parameter.
Powerful devices have significant drawbacks. When a significant force is applied through the current conductors, they begin to heat up. As you know, heat loss is the most common reason for reducing the efficiency of devices and this rule is also true for banks.
Number of ports
The ability to connect various devices to a portable battery will depend on the number of ports. The purchase of a power bank, in the case of which there are various connectors, will allow you to use one battery to charge a large number of gadgets.
In addition to standard USB ports that differ in size, such devices can also have a connector specifically designed for charging a smartphone in accelerated mode.
Weight and dimensions
As mentioned above, the weight and dimensions are inversely correlated with the capacity of the bank. For this reason, you should decide in advance which is better: a compact device with a small supply of electricity or a bulky battery with a capacity of 20 Ah and above.
When choosing a bank, you should also consider the performance of the smartphone battery.If the original gadget battery no longer provides continuous operation of the device on a single charge, then, despite the increased weight and dimensions, you should purchase a more powerful Power Bank.
Appearance and body material
Case material can also make a difference when selecting a new portable battery. Even if a light aluminum alloy is used as a shell, then in this case the mass of the device will be higher than when using a plastic product.
A more durable housing allows you to protect the product from destruction under significant mechanical loads. If the operation of the power bank will be carried out in conditions where the product may fall from a height, then devices made of metal should be preferred.
You should not neglect this rule, because in case of mechanical destruction of the lithium-ion batteries that make up the bank, they can explode, since lithium is a very inert substance.
Manufacturer
Buying a portable battery from well-known manufacturers allows you not to worry about the quality of the product. If you do not run into a fake, then such a device will last as long as possible.
The acquisition of products from lesser-known companies is a kind of a win-win lottery, but the “minimum prize” can really upset a participant in such gambling.
Extra features
In addition to such standard indicators as capacity, current, weight and dimensions, portable batteries can be equipped with additional options.
Moisture-proof and shockproof housing
If the casing of the bank is reliably protected from moisture, then such a device will not suffer even when completely immersed in water. Moisture-resistant device is ideal for fishermen and people involved in sailing.
The presence of a sturdy steel case is also an important feature for use in difficult weather conditions, as well as at high risks of the portable battery falling from a height.
With wireless charging
The presence of this option always affects the cost of the product, but you can overpay for the possibility of charging the smartphone without using wires. Failure of the connecting elements is one of the most common breakdowns.
Moreover, getting into the connector in low light conditions can be very difficult. If such inconvenience is already available, then you should give preference to choosing a device with wireless charging.
Before you try to charge your smartphone without the use of connecting wires, you need to make sure that the phone supports this function of power transmission.
With fast charge
The presence of the fast charging function allows you to completely restore the battery of the gadget in literally 1 - 1.5 hours. Up to 50 percent of the capacity can be charged in this way in 20-30 minutes.
The fast charge option is the most important feature, but only if there is not enough time to restore the electric capacity of the smartphone battery.
With solar panel
A good option for travelers and people living for a long time away from civilization is the purchase and use of a solar power bank. An indispensable condition for the use of such devices is the availability of sufficient sunlight.
The disadvantage of devices with solar panels is the increased fragility and the need for a large area for the placement of active elements.
With flashlight
Lighting elements can even be installed on budget models of portable batteries. The presence of a lamp will allow you to properly connect your smartphone to the bank even at night.
Typically, in such devices, LEDs are used as a radiator, so even prolonged lighting operation will slightly reduce the battery’s electrical reserve.
What models are worth paying attention to
A variety of models of portable batteries, as well as the presence of various additional options, often do not allow you to figure out which bank is the best in quality.
In such a situation, you should pay attention to models that have proven themselves in the process of operation. Such devices include:
- Hiaomi Power Bank 3 - the xiomi power bank of this model has a capacity of 10,000 mAh, minimal self-discharge, supports fast charging function.
- Digma DG-PD-40000 is a powerful power bank equipped with a display. There is a quick charge function.
- Asus ZenPower - an aluminum case, there is a charge indicator, capacity - 10050 mAh.
You can also assemble a high-quality power bank with your own hands, if you buy a case with electronic filling on Aliexpress and good batteries such as 16850.
