Alright, I need to write an original article about "Cordless Mini Chain Saw" using the provided context. Let me start by understanding the user's requirements. They want a 600 to 900-word article with natural headings, avoiding unsupported claims, and not mentioning AI generation. Also, the context includes specific products like STIHL GTA 26, Milwaukee M12 FHS 6", and DEWALT 20V MAX. Plus, there are links to bar oil and mentions of a video testing top 7 and the 5 best in 2026. First, the title should include the keyword. Maybe "Top Cordless Mini Chainsaws for 2026: A Comprehensive Review". That's catchy and SEO-friendly. Next, the introduction should set the scene about their popularity for pruning and light cutting tasks. Mention the need for a review based on testing the top models. The user provided a list of products to include. Let me outline the structure. After the intro, a section on key features to consider when choosing a model. Points like battery life, blade length, weight, and ergonomics. Then, detailed reviews of each product. The STIHL GTA 26 is highlighted as the best-selling garden pruner. Milwaukee's M12 Fuel Hatchet is another top contender. The DEWALT 20V MAX is also important. The user mentioned a $35 model from Amazon, which is an affordable option. Then there's the Top 7 and the 5 Best for 2026, which can be a section on the best budget options or the top picks. Need to make sure each section has a natural heading. Maybe start with an overview of the market, then key considerations, then individual reviews, and a conclusion. The bar oil links should be included as helpful resources. Also, mention the testing done in the video, but since it's a written article, frame it as results from testing. I have to avoid unsupported claims. So, for each product, I should stick to the provided info. For example, STIHL's performance in pruning, Milwaukee's lightweight design, DEWALT's battery life, and the Amazon model's affordability. The user also provided specific links for bar oil; include those as affiliate links but in a helpful manner. Check the word count. Let's aim for around 800 words. Introduction (100), key features (150), product reviews (500), conclusion (50). That adds up. Each product review should be concise, maybe 50-100 words each. Need to ensure that the links are placed appropriately, perhaps in a section about accessories or in the product reviews if relevant. Make sure to use the exact product names and models as provided. Avoid any markdown, just HTML tags like h2, h3, p, ul, etc. Also, natural headings mean they should read like a typical article, not forced. For example, "Key Features to Consider" instead of "What to Look For". Check that no unsupported claims are made. For example, if the user says "best-selling" about STIHL, that's okay. But if there's a claim like "the fastest", need to avoid that unless it's in the context. The user mentioned "best-selling" and "top 7", so those can be used. Include the bar oil links in a relevant section. Maybe after the product reviews, add a part about maintenance, suggesting the bar oil options. Use the exact links provided. Also, the user mentioned the 5 best for 2026, so the conclusion can mention that the article covers the top models and that users can find the best fit based on their needs. Need to ensure the flow is logical: introduction, key features, product reviews, accessories, and conclusion. Avoid any markdown formatting, just plain HTML. Check for any mentions of AI generation and remove them. Also, keep paragraphs short for readability. Let me start drafting each section, making sure to include all required elements and stay within the word limit. Use the provided context to structure each part accurately. Verify that each product is highlighted with its own subsection, and that the links are included where appropriate. Finally, wrap up with a conclusion that summarizes the key points and encourages readers to choose based on their
