Obligatory: this is Fasttech not Techfast.
A good charger for a good price, about $8 lower than Liitokala official store on AliExpress. Note that AliExpress add GST to the price, Fasttech don't. Free but slow delivery from Fasttech because it exceeds 20USD order value, but there are also faster shipping options at small extra cost, e.g. Epacket costs about $1.50 extra.
Note that this charger has a UK power plug. Liitokala don't sell this charger with an AU plug, so you'll need a mains plug adapter. The charger is also available with EU and US plugs if the UK ones run out, see the pull-down menu to the right of Fasttech's webpage.
If you want the additional ability to charge from your car's cigarette lighter, it'll cost you about $1 extra, again see the pull-down menu to the right of Fasttech's webpage.
The AUD price in the title assumes you don't let PayPal do currency exchange for you (adds about 4% to the price), and whatever is linked to your PayPal doesn't charge you "currency conversion fee" or "overseas purchase fee" as many credit cards do.
This is a proper smart charger, with battery test capability, and will let you know the capacity of your batteries so you can easily tell when one is failing. The charger will charge 1-4 batteries simultaneously, unless you select 2A charging (which is only available when lithium batteries are detected). You do not need to charge batteries in pairs like some cheaper chargers.

A good technical review of the charger is here: https://lygte-info.dk/review/Review%20Charger%20LiitoKala%20…
I recommend charging AAA eneloops at 500mA, AA eneloops at 700mA, and AA Eneloop Pros at 1A. This will give a long life to your batteries.
Expensive in my opinion
