I was a little bit skeptical at first because of how compact and small this device is, but wow, what an amazing little power pack to keep in the car! My car battery was completely flat, and this jump starter worked perfectly on the very first round. It started the engine instantly with zero fuss. It comes with very clear written instructions, and the video instructions on the desertcart page made it incredibly easy and safe to use. As a fantastic bonus, it also comes with a two-year guarantee warranty for peace of mind, and a lovely little storage baggy to keep everything neat and tidy in the vehicle. For the price and the small size, the power it packs is unbelievable. It has given me so much confidence and independence back. If you are on the fence about buying this, do not hesitate at all. It is worth every single penny and is a complete lifesaver! Review: Great and Useful Gadget - The product was delivered with proper instructions and all the requisite attachments. The pack was also well over half-charged when it was delivered. It is nice and compact in size, so hardly take up any storage room in the car. The instructions were easy to understand, and the charger itself is very easy to assemble and use. It also comes with a handy drawstring storage bag to keep everything together. It is USB charged so I can plug it in to charge in the car or take indoors and charge like my mobile phone - all nice and easy. My car battery was fairly new, but I haven't used the car that much over the festive period and then there was a sudden, nasty drop in temperature so the battery had drained out and the engine wouldn't turn at all. But this charger worked like an absolute dream! I used it after a quick top up of the power pack (just to make sure) and the car turned over immediately - no problem at all. Fantastic! It was quite a relief - brilliant! I live in the middle of the country and my nearest garage is nearly 6 miles off, so professional help is not close by. Having this charger means I'm no longer reliant on jump leads and the kindness of others if this happens again. So all in all, the charger is well worth the price. It's now essential kit in the car - it gives me a lot of peace of mind. ## Features - RELIABLE JUMPSTARTING PERFORMANCE: The AstroAI B8 jump starter powe pack can jump-start vehicles in extreme conditions ranging from -20℃ to 50℃ (-4℉ to 122℉). This jump starter powe pack easily jump-starts 7L petrol and 5.5L diesel engines, including motorcycles, sedans, SUVs, and other vehicles - COMPREHENSIVE SAFETY DESIGN: This car battery jump starter power pack is equipped with 10 built-in protections to ensure your safety. These include reverse polarity, overcurrent, overcharge, overdischarge, high & low temperature protection, reverse connection, overvoltage, overload, short circuit, and spark-proof protection - COMPACT AND PORTABLE: Weighing only 329g, this compact car jump starter power pack is a must-have for practical car accessories. It’s easy to carry and store anywhere, even in tight spaces, making it an excellent tool for both outdoor activities and emergency situations - EASY TO JUMPSTART: Insert smart battery clamps fully into the jump starter powe pack. Connect red clamp to battery positive (+), black to negative (-). Operate the jump starter by clamp indicators: Green light: Connection correct, safe to use; Red light + beep: Reverse connection. Reconnect terminals correctly. When clamp indicator is green, jump-start the car. After successful jump-start, disconnect the clamps - 5-IN-1 MULTIFUNCTIONAL: Beyond a battery jump starter power pack, it works as a portable power bank for your devices. The built-in LED delivers 3 practical modes: steady work light for roadside repairs, SOS for signaling help, and strobe for hazard warningβ€”keeping you safe and visible in any emergency - FULL SET OF ACCESSORIES: This package comes complete with B8 jump starter powe pack, smart battery clamps, a USB-A-C cable, a user manual, and a storage bag - WARM TIPS: Turn off all vehicle devices before jump-starting. If the engine doesn't start within 5 seconds, stop and remove the cables immediately. Do not leave the smart clamp plugged into the EC5 port (it drains power even when the vehicle is off). Do not use EC5-to-cigarette-lighter or any EC5 adapters to power dashcams or other devices – this will drain the battery to 0V and make it unchargeable. Use a 5V/2A charger (original cable preferred). Charge at 0–45Β°C. Recharge when battery is at 1–2 bars to prevent deep discharge. For best battery health, top up every 3 months ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FB2L7CCX | | Automotive Fit Type | Universal Fit | | Battery Capacity | 8000 Milliamp Hours | | Battery capacity | 8000 Milliamp Hours | | Battery cell composition | Lithium Polymer | | Best Sellers Rank | 40 in Automotive ( See Top 100 in Automotive ) 1 in Car Battery Jump Starters | | Brand | AstroAI | | Brand Name | AstroAI | | Compatible with Vehicle Type | Automotive | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 1,599 Reviews | | Included Components | AstroAI B8 Car Battery Jump Starter, Pack with Giftbox, Smart Jumper Leads, Storage bag, Use Manual and Warranty card, USB Cable | | Item Dimensions D x W x H | 8.3D x 16W x 2.8H centimetres | | Item Type Name | jump starter | | Item Weight | 650 Grams | | Manufacturer | AstroAI | | Manufacturer Part Number | B8 | | Manufacturer Warranty Description | 2-year manufacturer's warranty | | Model Number | B8 | | Product dimensions | 8.3D x 16W x 2.8H centimetres | | UPC | 810196490055 | | Unit Count | 1.0 count | | Vehicle service type | Automotive | | Voltage | 12 Volts | | battery-cell-composition | Lithium Polymer | ## Product Details - **Battery cell composition:** Lithium Polymer - **Brand:** AstroAI - **Product dimensions:** 8.3D x 16W x 2.8H centimetres - **Vehicle service type:** Automotive - **Voltage:** 12 Volts ## Images ![B8 Car Battery Booster Jump Starter Power Pack for 12V Vehicles (7.0L Petrol / 5.5L Diesel) and Motorcycles, Car Jump Starter Power Bank, Emergency LED Light & Full Accessories, Orange - Image 1](https://m.media-amazon.com/images/I/81nyNDZMyJL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Jump starter & Power pack to charge ur phone etc *by J***L on 28 May 2026* 5/5 Stars - Absolutely Brilliant and Highly Recommended!
