Power bank as battery: 18 Best Portable Battery Chargers (2023): For Phones, iPads, Laptops, and More

TSA battery rules: approved power banks & chargers

Travel often means long days for both you and your electronics. The best way to keep your devices charged throughout usage is by using a power bank. But, it can be tough to figure out what kind of mobile chargers fit within the Transportation Security Administration or Federal Aviation Administration’s rules so they won’t get taken away during check-in or at the security checkpoint.

All battery packs face very strict guidelines for air travel. Lithium-ion (rechargeable) batteries and portable batteries that contain lithium-ion can only be packed in carry-on baggage. They’re limited to a rating of 100 watt hours (Wh) per battery. With airline approval, you can bring two larger spare batteries (up to 160 Wh).

Here are our favorite battery packs that are within the FAA and TSA’s rules so you can keep your smartphone, tablet, laptop or headphones juiced up during long airplane rides. Whether you need a boost to keep binge-watching your favorite series or keep up with calls before boarding, these portable chargers will have you covered.

    Power Banks

    How to choose a good battery (Power Bank): 5 reasons according to an expert Vyrobniki try to change the energy savings with attachments and increase the capacity of the installed battery, but with an intensive Internet charge of the battery, everything is just over for one or two days. Yakshcho koristuvach perebuvaє at the settlement chi transport zasobi, tse bіda – zavzhd under the hand є charger attachments. Ale often-densely blame the situation, if the nearest electrician is a few days away. In such situations, it is best to win a special name for a battery – so the titles of “power bank”. I use impersonal models, with different characteristics and price parameters, and about those, how to choose a power bank, you can use this stat.

    What is the power bank

    Under the different name of Power Bank, there is a special model of a universal sound battery, which is composed of a set of lithium-ion or lithium-polymer elements, sch o rechargeable, combined into one battery, stored in a portable plastic, polycarbonate or a metal case, with a standard one or a dekilcom output. Different models of power bank for the phone vary in terms of battery capacity, design, equipment and other characteristics, but all stinks may be one thing – charging other mobile devices. To recharge the charge, power the bank enough to connect it to an electrical outlet (through a regular charger attachment) or to another sum-based attachment with a USB-output (mostly a computer or a laptop).

    How many times can I charge my smartphone or tablet? them charging your phone, dividing the capacity of the old battery into the capacity of the battery of a smartphone or tablet . But such a rozrahunok is not confirmed in practice: for example, the current battery for the phone is 10000 mAg, it is not possible to charge your mobile device again with a 2500 mAg battery. The reasons for this inconsistency are:

    • The voltage of the charged battery is 3.7 V, and the voltage of the charge is 5V. For the movement, a special controller is installed, which also saves energy in the process of changing the voltage;
    • spend at controllers connected to mobile devices;
    • battery self-discharge (especially after intensive use for many years).

    Therefore, if a portable battery is selected, it is necessary to insure the cost and overhead of the outbuildings with a 20-30% margin of capacity.

    Choose a power bank for capacity

    Find out about the characteristics of the power bank based on the battery capacity of the device. This indicator is the main one for any type of battery. Vіn vіmіryuєtsya in miliampere-years and by its value you can calculate how many times you can charge your gadgets with the full power of the bank.

    Whenever it is necessary to insure that, due to the increase in capacity, the jar will increase in size and capacity, choosing the battery for a particular outbuilding, it is necessary to change it, which will be handy for you carry an additional gadget in the gut or in a small bag. The reason for this is that the name of the battery is due in part to the type of mobile attachments. So, the original battery for telephones or smartphones with a battery up to 2000 mAh, in case of any other in the “Muslim” mode, the mother is to blame for the capacity of over 2500 mAh, and the axis for tablets is guilty of overestimating the value of 5000 mAh. Well, if you believe, how to choose a good power bank for a long journey or for a camping trip, then for such purposes it is better to use high-capacity batteries (10000 – 2000 mAh) near the metal case.

    Tricky choice

    Among the characteristics that indicate the strength of the victorious is a charging jet, which is a kind of power bank. Sound the wine to become 0.5 – 2 A. This indicator will inject the charge of the connected device. At outbuildings of great capacity, there are often є kіlka vіhodіv z vіznim strumu values, scho vіddaєtsya. In case of any trace, it is safe that these values ​​are most often seen in depressions, if only one attachment is connected for the charge.

    This is the same way to put respect for the strum, which is shown by the living block for the external battery. Sound the next warning to the outbuildings, in some streams of regular charging, a good stream, which is seen.

    Crime to ensure that charging mobile attachments to smaller ones, lower the passport with a strum, do not send them to shodi. It’s just that the process of charging will take longer. Even more often, when choosing a power bank among propositions of firms, coristuvachi do not pay attention to the presence in the main configuration of a power cord for connecting a “mobile phone”. If a suitable cable is available, you will need to buy an additional set of adapters or a cable of a necessary supply.

    Also, having added a new battery, turn on the roses for the connection of the wire adapter of the most appropriate jar. The best option is the splendid microU, but it is also fashionable to charge not only from electrical outlets, but also from a computer. Most of the economy class models will have light-emitting diodes for indication, and in expensive models – informative rare-crystal indicators.

    Well, for the sake of clarity, the choice of a specific model of power bank for your mobile add-on will fill in all the information in 5 steps:

    1. die in miliamper years. The more capacity, the more times you can recharge your mobile device;

    3. Battery capacity is also often stated by the manufacturer, but it appears to be moving. Therefore, it’s better to take an attachment from a little more, you need less;
    4. insure battery self-discharge. Charge the battery before a trip or hike. It is also necessary to know that the capacity of the batteries changes from time to time, regardless of which company to choose a power bank;

    Specifications for external batteries


    External batteries are made on the basis of lithium-ion and lithium-polymer batteries.

    Lithium Ion or Li-ion batteries look like AA batteries. They are inexpensive, have a low self-discharge rate, however, they are afraid of overheating and overcharging. Li-ion batteries can withstand up to 1000 charge cycles.

    Lithium polymer (Li-pol) batteries are made in the form of plates based on a polymer containing lithium. Li-pol batteries are more expensive than lithium-ion counterparts, more sensitive to overheating, but hold a charge better, weigh less and are designed for 1000 – 5000 cycles. To protect against possible fire, they need a special circuit. Also, lithium polymer batteries may not survive deep discharge.

    External battery capacity

    Capacity is a characteristic that is first looked for on the packaging or price tag. It depends on it how many times and which gadgets can be charged from an external battery. For energy-intensive devices and long journeys through wild places, models of external batteries with a capacity of 10-20 thousand mAh and more are produced. They are suitable for smartphones and for “gluttonous” laptops. For tablets, 10 thousand mAh is enough. An external battery for the phone must have a capacity of 2 to 2.5 times the capacity of the battery of the device.


    The parameter determines the charging speed. It is important that the portable battery and the gadget are compatible with current strength . Most smartphones need 1 – 1.5 A. A current of 2 A is suitable for tablets and other devices. If the phone is not equipped with a charge controller, it is better not to connect it to a portable source with such parameters.

    Connectors and cables

    Usually, external batteries are equipped with standard USB connectors and are supplied without a connection cable. However, there are options with built-in wires. Large capacity devices are supplied with laptop adapters. Theoretically, the more ports a portable battery has, the more devices are charged at the same time. In practice, use is limited by capacity: it should be enough for all gadgets. Therefore, it is not advisable to buy a small capacity power bank with several connectors .

    Charging methods

    Since the basis of a power bank is rechargeable batteries, the devices themselves also need to be recharged. According to charging method , they are divided into two types. Batteries powered by USB are connected to the appropriate connector of a computer, laptop or network adapter. Universal external batteries support charging both from a computer and from an outlet. In addition, there are models that can use solar energy.

    Tips for choosing an external battery

    • Small weight is not compatible with large capacity. The statement is especially true for lithium-ion batteries. When choosing a device based on them, remember that for every 5000 mAh of capacity, there is about 100 g of weight.
    • Don’t forget safety. Low-budget models, and even more so fakes from the Middle Kingdom, are not the best choice. Their manufacturers can save on overheating protection. The consequences are sad: the failure of an external battery, a rechargeable gadget, and even an injury to the owner of the device.
    • The shape and material of depends on how the power bank is intended to be used. If you do not plan to use the gadget during charging in the field, then you can buy a three-dimensional model. If you intend to continue using your phone while charging, it is preferable to purchase a compact ergonomic product. As for the material, plastic is a universal option. The material is light, it can be given any texture and color. If the priority is the strength of the device, then it is better to give preference to an external battery in a metal case.
