Accsoon TopRig 100W 4-Bay NP-F Fast Charger + EU G

The Accsoon TopRig NP-F (ACC-BC-01EU) is a four-bay charger for NP-F550, NP-F750, NP-F970 batteries and the corresponding Sony NP-F series, used in monitors, LED lights, and video equipment. Each slot charges independently; a 1.47″ color LCD display shows the charge level, current, power, and selected mode. USB-C PD 3.0 supports 9, 12, 15, and 20 V input. The “Smart” mode provides a total output of up to 90 W, while “Safe” mode provides up to 20 W. Automatic battery detection adjusts the charging process, and the reactivation feature helps restore batteries that have become undercharged after prolonged storage. This kit includes an EU GaN adapter and a USB-C cable.

Four Batteries Under Control

The Accsoon TopRig NP-F charges four batteries individually and displays their status on a color screen. You can select Smart and Safe modes with a single button. This package also includes an EU GaN power adapter.

Battery status displayed on screen

The 1.47″ color LCD shows each slot separately. In the graphic: 1 = current, 2 = power, 3 = input power, 4 = fully charged, 5 = charge percentage, and 6 = mode. Numbers 7 and 8 indicate the USB-C port and the mode button. The values shown in the image are examples of current status and do not represent guaranteed performance under all conditions.

Checking the Status Even Without an Adapter

Once an NP-F battery is inserted, its status is displayed even without a USB-C power source connected. This makes it easy to distinguish between charged and discharged cells when packing your equipment. NOBATTERY indicates an empty slot; POWERDETECTION indicates a charge check. Displaying the status does not charge the battery itself.

Power Output Based on Inserted Batteries

The four independent slots can charge batteries of various supported sizes simultaneously. Smart mode automatically adjusts the current based on the detected battery. Total output reaches up to 90 W; for fast charging of four batteries, the manufacturer recommends a 100W PD power source. A lower-wattage power source results in reduced performance or fewer simultaneously active slots.

Smart / Safe

Smart (1) offers up to 2.7 A per slot for NP-F750/770 and NP-F970/960; the manual for the NP-F550 specifies up to 2.4 A. Safe (2) limits the current to 0.6 A per slot. You can switch modes using a button; the available power depends on the connected power source and the condition of the batteries.

Undervoltage Activation

Hold down the mode button for three seconds to initiate an attempt to reactivate a battery that has not been used for a long time. The graphics indicate: 1—completed, 2—in progress, 3—reactivation mode, 4—failure, and 5—missing battery. This function may not restore a damaged or worn-out cell; check the result on the display.

Metal Base Dissipates Heat

Ventilation holes (1) and the CNC-machined metal base with fins (2) help dissipate heat when charging multiple batteries. Do not cover the ventilation holes, and do not leave the charger in a closed bag while it is in use. This detail explains the cooling design; it does not refer to an active fan.

The diagram indicates 1 for weight, 2 for width, and 3 for length. The base dimensions are 113 × 88 mm, and the weight is approximately 189 g. Remove the batteries before transport and use the charger in a dry, well-ventilated area.

Power Supply and Package Contents

This version includes an EU GaN AC adapter. The charger and its battery slots are the same as those on the standalone BC-01. The images show the charger; batteries are not included in the set. The packaging for the standalone BC-01 should not be confused with this set.
