# ASUNT Makita 18V USB-C Battery Adapter, PD 100W Max

ASUNT Makita 18V USB-C Battery Adapter is a battery-mounted charger and device power source with USB-C input/output and USB-A output. Its dual role may suit users who want to recharge a compatible battery or power small devices, but it cannot do both at once.

## At a glance

- USB-C is described as both an input for recharging a compatible battery and an output for charging devices.
- The listing specifies a separate USB-A QC3.0 output rated at 24W.
- An LED display is claimed to show battery level and charging status. The listing says discharging the battery is needed to calibrate its displayed level.

## Pros

- Two-way USB-C use offers a way to recharge a compatible battery or use it as a power source for devices.
- USB-A and USB-C outputs give options for charging different devices.
- The LED display is intended to show battery and charging status.

## Cons

- It cannot accept input and provide output at the same time.
- The listing says it only charges 18V batteries and warns against charging a battery below 18V.

## Before you buy

- The listing says the adapter fits specified Makita 18V batteries and other compatible models, but cannot fit batteries from other brands. It also says not to charge a battery below 18V, and that input and output cannot operate at the same time. The approximately 40-minute full-charge claim is stated for 20V/5A and 18V/5A batteries. The LED level may be inaccurate until the battery is discharged to calibrate it. The claimed 100W USB-C rating is a maximum, not a stated guarantee for every device or charging condition.

## A good fit for

- Makita 18V battery owners seeking USB-C device charging or a way to recharge a compatible battery through USB-C.
- People carrying phones, tablets, cameras or other listed devices who can accept the adapter's battery and simultaneous-use limits.

## Less suited to

- Owners of battery brands other than Makita.
- Anyone needing the battery to charge while the adapter powers another device.
- Users who need to charge a battery below 18V.

## Customer feedback

Only an aggregate rating is supplied, based on a single rating, so it offers very little evidence about real-world experience and cannot establish how well the adapter performs. Consider the listed battery compatibility, simultaneous-use restriction and display calibration caveat when deciding whether its features suit your needs.
