10 thin external batteries

You can take a thin, lightweight bank with you wherever you go. On a long trip, it will recharge your smartphone, tablet, MacBook and other electronics.

When choosing a bank, you must remember that not every device is universal. To quickly charge the flagship smartphones, an external battery must support the Quick Charge 3.0 standard. To power laptops, you need something else: a Type-C connector, an output voltage of more than 12V and a cable compatible with high current ratings.

We already had collections dedicated to portable batteries, in which we focused on capacity and charging speed. Almost all of them look massive and weigh a lot. Constantly carrying them in your pocket is a dubious pleasure, so this time the main criterion will be the thickness.

Below you will find a selection of portable chargers for smartphones and laptops. Their common feature is a thin body, so they can easily fit in a jacket pocket, handbag and even a wallet. The minimum capacity of 10,000 mAh is enough to recharge the Samsung Galaxy S10 and the latest iPhone 2-3 times.

Portable chargers produce many tech brands, but not everyone has compact and lightweight products. Our favorites in this category are Anker, Moshi and Tronsmart. Let's start with them.


Anker PowerCore II Slim 10,000

But it is worth noting that the cable from the delivery set of accelerated power does not provide: with it, the current is supplied in the normal mode 5 V / 1.5A-2.4 A. In order to energize the mobile phone for the shortest possible time, you must use the cable from the kit to the smartphone.

Xiaomi Mi Power Bank Pro 10,000

Price: 1 449 rubles

An inexpensive Xiaomi charger does not greatly weigh a pocket. It is able to charge the popular iPhone 7 and iPhone 7 Plus more than three times. Full charge of most modern flagships will take him about two hours. It has support for Quick Charge 2.0, but there is no Power Delivery, so Google Pixel smartphones will charge in standard mode with a current of 2A.

Baseus Choc universal power supply independently detects the type of device connected and selects the desired power supply mode.

This is one of the latest Baseus models. It is distinguished from old by reduced dimensions. There is absolutely nothing on the case - no LEDs or buttons. On the one hand, I would like to praise for such a minimalistic approach to the manufacturer’s design, but on the other hand, to criticize: it’s very difficult to track the battery charge level without indicators.

Baseus Choc has high efficiency, when using any connector, the current strength reaches 2A. A reliable protection system will protect the Verbank and the equipment connected to it from short circuits, overheating and power surges.
