UWell Caliburn KOKO. Looking back on 2019, one of the best devices released was the UWell Caliburn. Performance vs price, the Caliburn was and still is hard to beat.

UWell Caliburn KOKO Kit packaging

The UWell Caliburn KOKO comes in a sleeved black box. The kit comes complete with the unit, 2 pods, a short micro USB cord, and a fairly robust neck chain. No complaints about the packaging -UWell has always been fairly consistent with decent packaging.

Fit and Finish:

The Uwell Caliburn KOKO seems to use the same aluminum alloy construction for the square-shaped KOKO. The matte finish is fairly scuff resistant in normal day-to-day use and really, unless you pocket this with coins and keys – or drop it on concrete or gravel – you have nothing major to worry about. My original Caliburns are still in great shape 9 months later. The micro USB port is on the bottom and there is a tiny LED indicator for battery life on one side.

The Caliburn KOKO is currently available in 4 colorways – Red, Blue, Black and Grey.


Uwell Caliburn KOKO Pod

UWell opted for a slightly different pod for the KOKO. Same design, shape, and 2mL capacity – but the coil has been changed to a 1.2 ohm and the airflow is slightly tighter for better MTL vaping. The new pod uses the same cap and fill ports as the OG – they are still a bitch to fill with a glass dropper. As pointed out by a reader, the Koko pod does have 4 wicking holes – 2 large and 2 small – as opposed to just the 2 on the original pod. This probably helps wicking higher mg traditional nic e-liquids in VG heavy mixes. The KOKO pods are easily identified by the red base.


The newer KOKO pods are great. The more restricted draw is much better for MTL hitters. The KOKO renders excellent flavour and decent vapour production ( given there’s less airflow). Airflow-wise – we’re probably talking what “feels” like 3/4 of the airflow as compared to the draw of the original Caliburn.

I tested the KOKO with both 20mg nic salt and 6mg traditional nic with no issue. The large juice hole on the coil ensures you can use a 70/30 ratio traditional nic without worrying about wicking. Pods are cross-compatible with the original Caliburn. Battery life is the same as the Caliburn – as the battery is the same 520 mAh. The major difference is the KOKO is draw-activated only – there is no fire button. The draw activation is smooth and consistent -much as it was with the original Caliburn.


It’s funny so many readers left a poor user rating on my original Caliburn review. The Caliburn remains one of the best pod devices out there and replacement pod sales will verify that. The KOKO adds a different form factor to the mix. If you already have a working Caliburn, I wouldn’t run out to buy this – just the new pods if MTL is your style… but it’s worthwhile if you don’t already have one.

The package of Caliburn KOKO Pod System Kit includes:

UWell Caliburn KOKO Kit contents

● 1 x Uwell Caliburn KOKO

● 1 x 1.2ohm Caliburn Pod

● 1 x MicroUSB Cable

● 1 x User Manual

● 1 x Warranty Card

The UWell Caliburn KOKO is a great addition to the UWell family. Pricing is similar to the original Caliburn as is the pricing for the new 1.2 ohm pods.
