My Makita batteries usually just sit around collecting dust between my big DIY projects. I hated that those expensive 18V packs were doing absolutely nothing while my phone died or I got sweaty in the garage.
I found this adapter and fan combo on AliExpress and figured it was worth a shot for the price. This Power Tool Parts BL1830 USB TypeC Charger Power Bank Electric Fan Desktop Table Fan for Makita 18V Li-ion Battery BL1815 BL1860 review covers how it actually performs in the shop.
What is this tool adapter?
At its core, this is a plastic housing that clips onto your existing Makita 18V battery. It turns that battery into a portable power station and a desktop fan.
You get a USB-C port for charging your devices and a small fan head for cooling. Many sellers offer this with free shipping, which makes the low price even more attractive if you are trying to be budget-friendly.
Real world testing
The fan itself is not going to replace a big shop fan, but it moves enough air to keep you cool when you are hunched over a workbench. I mostly use it to keep air circulating while I am soldering or doing fine detail work.
Using the USB-C port is the real reason I bought this thing. Being able to charge my phone or a small work light using a battery I already own is super convenient during a power outage or a long day working in the yard.
Honest pros and cons
- Pros
- It gives a second life to your idle batteries.
- The USB charging is surprisingly fast for a tool adapter.
- It is very lightweight and easy to throw in a tool bag.
- Being able to use your existing tool batteries is a huge cost saver.
- Cons
- The plastic casing feels a bit cheap compared to name-brand tool gear.
- Shipping from overseas can take a few weeks to reach your door.
- There is no official warranty if the internal electronics fail.
- You have to be careful not to drain your battery too low or it might not charge back up on a standard tool charger.
Who should buy this?
If you are a hobbyist who already owns a pile of Makita batteries, this is a fun gadget to have around. It is perfect for people who work in sheds, garages, or outdoor spots where finding a wall outlet is a total pain.
You should probably skip this if you need professional-grade, rugged gear that can survive being dropped from a ladder. It is a plastic accessory, not a heavy-duty tool, so treat it with a little bit of care.
What other buyers say
Most people seem to love the convenience of the USB port. One user mentioned that they keep theirs in their camping kit to charge phones and keep the air moving in a tent.
Another buyer pointed out that the fan is surprisingly quiet for its size. People generally agree that for the low price, it does exactly what it says on the box.
Final verdict
This device is a clever way to get more value out of your existing collection of batteries. I have been using mine for a few months now, and it has not let me down yet.
It is not a piece of high-end equipment, but it is a handy tool to have in your kit. If you want a budget-friendly way to stay cool and charged up while working, this is a solid pickup.
