New Product from Xiwu: S1 Pod System Review Report

This time, we received the new S1 pod system from Xiwu, featuring a midnight blue color scheme.

The upper part of the device has a non-slip mesh sleeve made of PCTG plastic, while the lower part is made of aviation aluminum. The mouthpiece design of the S1 is more ergonomic, with a rounded shape that fits the lips, finally avoiding the discomfort of the previous generation P1's square mouthpiece. The cartridge connects to the device magnetically, but unfortunately, the tolerance control in this version is not perfect, resulting in a noticeable gap at the connection point, causing the cartridge to wobble when shaken. I hope the brand can improve this.

Inserting the cartridge prompts the battery level indicator. The breathing light shows the current battery level: 4 white lights for 75% and above, 3 white lights for 25-50%, 2 white lights for 10-25%, 1 white light for below 10%, and 4 red lights for insufficient battery. 【Single Rating: 8.5/10】

Flavor Restoration and Throat Hit:

Each cartridge has a capacity of 1.3ml, with a ceramic core heating element and a resistance of 1.5Ω. The biggest feature of the Xiwu S1 product is the use of the latest Nicotine X patented formula technology, which only uses 1.7% nicotine content, providing just the right head rush and a clearer throat hit, offering smokers a new craving relief option rather than a new source of addiction.

No. 3 Aroma: Nicotine content 1.7% (20mg/ml), strong throat hit satisfaction.

The first puff feels quite unique, with a sensation reminiscent of white liquor going down the throat, slowly revealing a mild herbal tobacco flavor, with a hint of tea-like aftertaste, reminiscent of oolong tea. There is no unpleasant tar taste added, nor the common buttery tobacco or nutty tobacco flavors. This flavor has a distinct throat hit, making it very satisfying to vape. As a long-time smoker, I found myself wanting to finish a cartridge, which was quite surprising. 【Single Rating: 9/10】

Lemon Oolong Tea: Nicotine content 1.7% (20mg/ml), moderate throat hit satisfaction.

The first puff reveals the aroma of lemon peel, followed by a flavor similar to honey grapefruit tea, with a rich oolong tea taste in the aftertaste. The sweetness is controlled to be slightly sweet, balancing the astringency of the tea without being overly sweet. This flavor has a heavier overall tone, and the lemon flavor is not particularly prominent with continuous puffs; the tea flavor tends to dominate, making it feel more like grapefruit tea. This flavor is suitable as a refreshing option. 【Single Rating: 8/10】

Hazelnut Red Bean Ice: Nicotine content 1.7% (20mg/ml), moderate throat hit satisfaction.

Unlike the common mung bean flavor, the entry is a soft red bean paste, accompanied by a milky flavor, reminiscent of glutinous red bean cake. The aftertaste has a faint hazelnut flavor, with an overall pairing leaning towards pastry, making it a very satisfying flavor. 【Single Rating: 9/10】

Vapor Production and Draw Resistance:

The Xiwu S1 innovatively applies MEMS differential pressure sensor technology (commonly used in smart safety control systems) to replace traditional airflow switches, monitoring the strength of the inhalation airflow in real-time, thus controlling the battery output power to personalize and stabilize the heating power of the e-liquid. This means the S1 can intelligently adjust vapor production based on the smoker's inhalation habits, providing a truly customized experience. #p#分页标题#e#

The draw resistance is relatively high, but it does not feel difficult to inhale. Personally, I quite like this draw resistance; it feels tight and satisfying, similar to smoking a cigarette.

Leakage:

No leakage has been encountered so far. 【Single Rating: 10/10】

Condensate:

The correct inhalation posture is very important; avoid lying down, side inhalation, or reverse inhalation, which are common sense when using small pods. The No. 3 Aroma cartridge has experienced some gurgling sounds due to condensate accumulation, and the brand has addressed this issue. 【Single Rating: 6.5/10】

Oil Explosion:

No oil explosion phenomenon has been encountered. 【Single Rating: 10/10】

Burnt Core:

No issues with burnt cores have been encountered during normal frequency use. 【Single Rating: 10/10】

Battery Life:

The battery capacity is 350mAh, using a Type-C charging interface, with a charging time of about 45-60 minutes. 【Single Rating: 8/10】

Overall Evaluation:

The Xiwu product has two major highlights: Nicotine X technology and MEMS differential pressure sensor technology. The former aims to provide a full throat hit satisfaction with lower nicotine content, while the latter offers customizable vapor production. The No. 3 Aroma flavor provided an unexpectedly satisfying experience, allowing me to continuously vape a tobacco flavor in a pod system for the first time. The flavoring style and concept are quite innovative. Since this is a beta unit, some details are not fully polished and need refinement, but overall, my vaping experience was far better than the previous generation product. I hope to see a more perfect experience after improvements in the future. 【Overall Rating: 8.5/10】
