BlitzWolf BK-385: 48 W Charger with Four USB-A Ports and QC 3.0

The BlitzWolf BK-385 is a mains charger with four USB-A ports and a stated total output of 48 W. It supports Quick Charge 3.0 and has an integrated European plug. It is particularly useful for charging several devices from one socket using USB-A cables.

Four devices from one socket

The charger can replace several individual adapters on a bedside table or in a travel bag. You could connect a phone, headphones, a watch and a power bank, for example. A cable can also have a USB-C connector at the other end: USB-A describes the connector on the charger side, not necessarily the one on the device side.

The 48 W figure applies to the charger as a whole, not to each port. When several devices are charging, power is shared between the outputs, and each port has its own limit. Four connected devices may therefore not all charge at their maximum speed.

This setup can be practical for a phone and a few smaller accessories. If you want to fast-charge a tablet and several phones at the same time, however, the limited total output may slow charging down.

Quick Charge 3.0 and port output

The BK-385 supports Qualcomm Quick Charge 3.0. A compatible port is listed with an approximately 18 W profile, but that does not mean every port can deliver 18 W simultaneously. Quick Charge 3.0 adjusts voltage over an approximate range of 3.6 to 12 V according to the needs of a compatible device.

A compatible Android phone may therefore charge faster than it would from a standard 5 V / 1 A adapter. Actual speed depends on the charging protocol supported by the device, the port and cable used, and the other devices connected. Not every phone uses Quick Charge.

USB-C devices can connect, but USB-C PD is absent

All four BK-385 outputs are USB-A. You can connect a phone or accessory with a USB-C port using a suitable USB-A-to-USB-C cable, but the charger has no USB-C port for USB-C Power Delivery charging like a modern USB-C adapter. Some sales descriptions mention PD, but USB-A ports do not replace a USB-C PD output.

An older iPhone with a Lightning connector can be connected using a USB-A-to-Lightning cable. Charging speed depends on the particular iPhone and port. An iPhone with USB-C needs a cable with the appropriate connector. In neither case does the BK-385 offer modern fast charging via a USB-C PD output. A charger with a USB-C PD output is a better choice if you want to use that standard with a phone or laptop.

Dimensions and travel

According to a European distributor, the adapter measures approximately 86 × 50 × 30 mm. Its European plug is integrated into the body, so it does not need a separate mains cable to connect to a socket.

The input is rated for 100–240 V AC at 50/60 Hz, which is useful for travel. Whether you need a physical plug adapter depends on the socket type in the destination country, not simply on whether that country is in the EU.

Distributor information lists the casing material as PC + ABS and mentions protective features. Leave room for heat to dissipate and do not cover the charger, especially when all ports are in use.

Key specifications

Who is the BK-385 for?

The BK-385 is practical for someone with several USB-A cables who wants to charge a phone and small accessories from one socket. One Czech user review reports that Quick Charge worked, but a single experience does not guarantee the same speed with every combination of device and cable.

Before buying, the main things to consider are the lack of a USB-C PD output and the shared 48 W limit. It could serve well as a four-port charger for a watch, headphones, power bank and phone. It is not a suitable replacement for a higher-powered USB-C PD adapter for a laptop or a phone with greater fast-charging requirements.
