There are a few brand-less external batteries of this nature on trademe, however I don't trust anything unbranded as you just don't know what type of batterycells they are using.

There is a lot more selection on Amazon and abroad.

Ideally I'd want something decent (but not huge in size) so perhaps around 70 Wh?

Many REPUTABLE online sellers simply can no longer send batts to NZ, its simply no longer legal to air freight them , they are classed as dangerous goods.

IF detected at customs/nz post, it WILL be destroyed .

So you can't buy a laptop online and have it shipped to NZ either?

Yes but not via normal post. Fedex will do (for example) it but they have special guidelines.

Get an empty pack off aliexpress/ebay and fill it with your own cells then?

Why not just buy a spare battery?

I have been thru that with my old dell which had a detachable battery.

Problems are, chargers are not readily available for the bare battery, you have to hibernate or shut down to swap the battery, and it means you are cycling the laptops own battery considerably more. An external pack for when away from power means that it is what gets cycled, the laptop remains at full till the external one is out, so you put less cycles on the more expensive laptop battery.

Also, not all laptops have a swappable battery now, the slim ones all have internal lipo pouch cells.

Good point, my work laptop doesn't have a removable battery.

You can buy what ever you want , Some companies dont care & will ship regardless.
As I said, if detected at customs or by NZ post , & it hasnt been sent as dangerous goods, by an approved carrier, by approved methods, they can & do just destroy.

This has been happening for months now, packages with batts being destroyed at the border .
Some stuff gets through they cant check every parcel, but some parcels are getting confiscated.

btw, a separate external batt unit would be looked upon differently that a laptop I would think.

Thanks for all the responses. Yes my laptop (surface pro) doesn't have a detachable battery.

There are few brand products here and there locally Lenmar, Fondi etc, just wondering if anyone has any real experience with these types of devices.

A heap of these "jump starter" external battery devices on trademe, but I'm concerned about the potential for low quality battery cells.

I keep buying old HP Elitebooks off amazon because they have the standard normal ~30wh battery, and then a slice battery that clips on the bottom which holds another ~30wh. Its good for about 8-10 hours with the SSD.

The Elitebook with its normal battery and slice battery can dock within its docking station too which is quite cool.
I think it would be quite cool if i could stack up slice batteries on the bottom but they didnt design it like that.

It seems no company makes such devices anymore that meet my needs of a long external battery and digitiser stylus with an internal storage bay for the stylus.

I had my hopes up with the Lenovo Thinkpad 10 tablet but the keyboard doesnt have a battery in it and no replaceable internal battery.

So my only suggestion is some sort of generic external battery pack.
