Xtar VC8 eight-bay charger with LCD screen

The essentials

The VC8 suits anyone with a large cell collection: eight independent bays, a large LCD screen showing voltage, current, capacity, and internal resistance for each cell, and a grading function to sort cells by health. USB-C QC3.0 power reaches up to 3A on a single bay, with five currents to choose from to adapt charging. The logical trade-off of eight bays is a real desk footprint, and reaching the full 3A requires a suitable Quick Charge adapter. For anyone wanting to charge and analyze a large number of cells without multiplying chargers, it has few rivals at this price.

Strengths

  • Eight independent bays, enough to charge an entire cell collection at once
  • Detailed LCD screen: voltage, current, capacity charged, and internal resistance per bay
  • Real capacity testing and a grading mode to sort cells by health
  • USB-C power with QC3.0 fast charging, up to 3A on one bay
  • Five selectable currents (0.25 to 3A) to adapt charging to each cell

Limitations

  • Logically bulky footprint with eight bays occupied
  • The stated 3A requires a suitable USB-C Quick Charge adapter upstream
  • No mention of LiFePO4 compatibility, unlike some rivals in the range
  • No backup USB output, unlike more versatile models like the Xtar X4
  • No reactivation function for cells dropped to zero volts is mentioned on the product page

The charger for large cell collections

The Xtar VC8 is a smart eight-bay charger, built for users with lots of cells: flashlight, vaping, RC hobby, or battery pack enthusiasts. It plugs in via a simple USB-C cable and automatically detects each inserted cell's chemistry.

8
Independent bays
3 A
Max current (1 cell)
26650
Largest supported Li-ion format

From 10440 to 26650, plus NiMH and NiCd

Its compatibility is broad: Li-ion and IMR cells from 10440 to 26650, including 14500, 16340, 18650, 20700, and 21700, as well as rechargeable NiMH and NiCd batteries in AA, AAA, and C sizes. All eight bays are independently managed, so you can charge eight cells of different types, sizes, or charge levels at once.

A large LCD screen that goes beyond charging

The LCD screen shows in real time, for each cell, the voltage, current, capacity charged, and internal resistance, valuable data for spotting a tired cell. The VC8 also offers a real capacity testing function and a grading mode that sorts cells by health, useful for building matched pairs or uniform packs.

USB-C QC3.0, up to 3A with the right charger

Powered via USB-C with QC3.0 fast charging, the VC8 delivers up to 3A on one bay and offers five selectable currents (3A, 2A, 1A, 0.5A, and 0.25A) to adapt charging to each cell.

Worth planning for: to fully benefit from the stated 3A, a USB-C Quick Charge compatible adapter is needed upstream. A standard USB supply limits charging speed.

Eight bays, a footprint to match

Sturdy and complete, with protection against overheating, overvoltage, and short circuits, the VC8 accepts a bulkier footprint than the four-bay chargers in the same lineup, a logical trade-off for its eight bays. No backup USB output is offered, unlike the Xtar X4, which can rescue a phone.

Who the VC8 is for

This charger suits anyone with a significant collection of 18650, 21700, or AA/AAA cells to recharge and analyze regularly, without multiplying four-bay chargers. For more compact daily use, the Xtar VC4SL already covers internal resistance on four bays. For true diagnostics with external probes and REFRESH mode, the Xtar Dragon VP4 Plus goes further.

Frequently asked questions

Eight, in independent bays. You can charge eight cells of different types, sizes, or charge levels simultaneously, each tracked separately on the LCD screen.

Li-ion and IMR cells from 10440 to 26650 (18650, 20700, 21700...) as well as NiMH/NiCd batteries in AA, AAA, and C sizes. It automatically detects the chemistry of each inserted cell.

Yes. It offers a real capacity testing function and a grading mode to sort cells by health, in addition to showing the internal resistance of each cell.

Yes, the stated 3A on one bay requires a USB-C Quick Charge (QC3.0) compatible adapter. With a standard USB supply, charging stays slower.
