Recommended lightweight and thin mobile battery for laptops: Emphasis on portability

2020/1/12020/1/15

The purposes and merits of using mobile batteries for laptop computers are as follows.

• No need to look for a seat with an outlet on the go or in a cafe
• As heavy as an AC adapter, compact
• Can be used for long hours and with high loads without worrying about the remaining battery power
• You can also charge your tablet or smartphone

During this time, I researched various products before purchasing, so I will introduce the ones that I thought were good.

Important points when choosing

Therefore, in selecting this time, we emphasized the following.

• Weight, size (500g or less)
• Battery capacity (10,000 mAh or more)
• Brand
• USB Power Delivery compatible
• Mobile battery output format

Weight, size

Because I was thinking of using it when traveling by bullet train or airplane, or at a cafe, etc.Lightness and size that do not get in the way of carrying are the main premise.

Battery capacity

There is a trade-off between battery capacity and weight / size.Most lightweight notebook PCs have a battery capacity of 5000 mAh or more, soCapacity to fully charge your laptop at least onceI want it.

Brand

Batteries are products that store high energy.If possible, I would like to choose from manufacturers with high product quality and proper support.

Supports USB Power Delivery (USB PD)

USB PD is a power supply standard via USB Type-C.Charging with a voltage that is not suitable for the device may cause a malfunction.When charging according to the USB PD standard,According to the connected deviceThe output voltage can be switched automatically to charge., Tablet orMobile notebook can also be charged..Select from the corresponding ones.

output method

There are three main types of mobile battery output formats: (3) USB type C (XNUMX) DC (XNUMX) outlet.With the outlet type, in addition to the mobile battery, you also have to carry a personal computer charger (AC-DC adapter), which increases your luggage.Therefore, no outlet is requiredThose that can output USB or DCI chose.
Also, the larger the maximum output (wattage), the faster the battery can be charged.If it is too small, it will not be able to charge or it will take time to charge.This is the output of a general notebook PC AC-DC adapter.30-45W or more is safe.

Recommended mobile battery for notebook PC

For notebook PCs that do not support USB type C power supply

Eur-lex.europa.eu eur-lex.europa.eu	17,400 mAh (for about 1.5-3 charges)

Others	With DC conversion plug

The biggest advantage is that you can use both USB and DC as the output method, and it has a DC conversion plug.Some older PCs don't support USB type-C charging and require an AC-DC adapter, but you can charge it directly from the battery with a DC conversion plug.
In addition, since the output is as high as 65W, you can quickly charge a computer using a 65W AC-DC adapter.The weight is also the lightest among the large-capacity mobile batteries for laptop computers.

For notebook PCs that support USB type C power supply

Eur-lex.europa.eu eur-lex.europa.eu	20,100 mAh (for about 2-4 charges)
weight	434 g
Price	¥ 9,980 ~

This is the previous one700-BTL033BKCompared to, it does not come with a DC conversion plug, but it is about the same light and can be purchased cheaper.The latest laptops can be powered by USB type-C, so if you don't need a DC plug, this is the way to go.

Anker also sells products with almost the same specifications.

For those who want lightness and battery capacity

Eur-lex.europa.eu eur-lex.europa.eu	14,000 mAh (for about 1.5-2.5 charges)

This is the lightest class with a weight of 300g or less.That's less battery capacity, but 14,000 mAh should still be enough.It looks compact, stylish and nice.

For those who value cheapness and lightness

These are recommended if it is reasonably priced and you can charge it about once.It is considerably lighter because the battery capacity is small.However, some of them do not have low output, so charging may be slow.

Summary

The mobile batteries for laptops introduced this time are summarized in the table.It was enough for me to charge one time with a notebook PC + mobile battery, so I chose it with an emphasis on lightness.We hope it will be helpful when selecting weight, battery capacity, price, etc.
