Silicon Power brand portable battery can be attributed to the budget solutions of the market. The model received a textured plastic case, which should not slip out of the hands, and is also complemented by an information display that shows the current charge level of the lithium-polymer battery. The capacity of the latter is 20,000 mAh (74 Wh), of which 12,600 mAh can be directly transferred to connected mobile devices.

This, for example, should be enough for 4 charging cycles of the Apple iPhone 12 or 1.5 recharges of the Xiaomi Redmi Pad tablet. To transfer energy to gadgets, there are two USB A with a peak power per port of 10.5 watts. The Silicon Power GS28 20000 Power bank can be used to charge two devices at the same time. To replenish the capacity of the power bank itself, not only microUSB is offered, but also the increasingly popular USB C connector (but it only works for “input”). It should be noted that charging the battery from 0 to 100% will not be fast (it is stated that it takes about 11 hours), however, you can count on a high level of security, because the smartSENSE function is implemented here (automatically sets optimal performance) and 11-level smartSHIELD protection system.

At 35%, it fades. At 95% it doesn't charge anymore. After 1.5 months, the display is no longer working. Enough for 10 charge cycles. Service center Silicon power in Ukraine is not available. In the USA and in Russia. But it’s too expensive for diagnostics and not too expensive. Never buy Silicon power. Cupping at the Vodafone store. They didn’t take it for repairs, because they didn’t want to send a check.

1.5 months of work and that's it.

A nasty power bank with a protective display. Battery capacity is small.

He's doing quite a bad job. Fully charging. It is already sold around the same time as the date of purchase. Nice design and plenty of ports. I scribble at work and at home. Form factor and color per price. Having helped with blackouts a dozen times, the router did not cause any problems with power supply. Dry technologies for unstable voltage.
No heating
The last 10% of the battery takes a very long time to charge
Not always the display works well
