Each bay identifies the inserted cell type automatically and applies a suitable charging profile for lithium-ion (3.6\/3.7 V), lithium iron phosphate (3.2 V), 1.5 V lithium rechargeable cells, and standard 1.2 V NiMH batteries. Its USB-C power input and independent slot control make it suitable for mixed-chemistry charging scenarios without manual current selection.\u003c\/p\u003e\n\u003cp\u003eThe charger accepts a broad range of cylindrical formats, from small 10440 cells up to unprotected 21700 batteries, as well as AA\/AAA 1.5 V lithium and NiMH types. A mode switch allows the user to select between a general charging mode and a LiFePO?-specific mode, ensuring correct voltage and termination behaviour. Charge progress is shown through individual LEDs, and built-in protections manage over-charge, short-circuit conditions, and activation of deeply discharged cells where appropriate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour independent charging slots capable of handling different chemistries simultaneously.\u003c\/li\u003e\n\u003cli\u003eAutomatic recognition of Li-ion, LiFePO?, 1.5 V lithium, and NiMH cell types.\u003c\/li\u003e\n\u003cli\u003eSupport for a wide range of cylindrical sizes including 10440, 14500, 16340, 18350, 18500, 18650, 18700, 20700 and unprotected 21700.\u003c\/li\u003e\n\u003cli\u003eCompatibility with AA\/AAA 1.5 V lithium and AA\/AAA\/A\/SC NiMH cells.\u003c\/li\u003e\n\u003cli\u003eSelectable standard and LiFePO? charging modes.\u003c\/li\u003e\n\u003cli\u003eAutomatic charge termination based on chemistry-specific detection methods.\u003c\/li\u003e\n\u003cli\u003eLow-voltage activation for suitable over-discharged cells.\u003c\/li\u003e\n\u003cli\u003eLED indicators for real-time charge status on each slot.\u003c\/li\u003e\n\u003cli\u003eMechanical support for batteries between roughly 34 mm and 70 mm in length.\u003c\/li\u003e\n\u003cli\u003eNot compatible with protected 21700 cells due to extended length.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Xtar MX4 Mini Mixer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlots:\u003c\/strong\u003e 4 independent charging bays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported chemistries:\u003c\/strong\u003e Li-ion 3.6\/3.7 V, LiFePO? 3.2 V, 1.5 V lithium rechargeable, NiMH 1.2 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e USB-C, 5 V 2 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging current:\u003c\/strong\u003e Up to 1 A on two slots, or 0.5 A when all four slots are used\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eNo limit — charger detects full charge via battery voltage; display caps at 9,999mAh but full charging is unaffected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery length range:\u003c\/strong\u003e Approx. 34–70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported Li-ion sizes (3.6\/3.7 V):\u003c\/strong\u003e 10440, 14500, 16340, 18350, 18500, 18650, 18700, 20700, unprotected 21700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported NiMH sizes (1.2 V):\u003c\/strong\u003e AAA, AA, A, SC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported 1.5 V lithium sizes:\u003c\/strong\u003e AA, AAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging modes:\u003c\/strong\u003e Standard mode and LiFePO? mode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge indication:\u003c\/strong\u003e LED status lights per slot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection features:\u003c\/strong\u003e Over-charge, short-circuit, and low-voltage activation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported 21700 types:\u003c\/strong\u003e Unprotected only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Xtar","offers":[{"title":"None","offer_id":44553842622506,"sku":"XTA-CH-03252","price":8.95,"currency_code":"GBP","in_stock":true},{"title":"Inc USB-C Wall Adaptor + 4 x AA Lithium Batteries","offer_id":44553842655274,"sku":"XTA-CH-03265","price":31.95,"currency_code":"GBP","in_stock":true},{"title":"Inc USB-C Wall Adaptor + 4 x AAA Lithium Batteries","offer_id":44553842688042,"sku":"XTA-CH-03254","price":26.95,"currency_code":"GBP","in_stock":true},{"title":"Inc USB-C Wall Adaptor + 4 x AA \u0026 4 x AAA Lithium Batteries","offer_id":44553842720810,"sku":"XTA-CH-03255","price":44.95,"currency_code":"GBP","in_stock":false},{"title":"Inc 4 x AA Lithium Batteries","offer_id":44553842753578,"sku":"XTA-CH-03256","price":26.95,"currency_code":"GBP","in_stock":true},{"title":"Inc 4 x AAA Lithium Batteries","offer_id":44553842786346,"sku":"XTA-CH-03257","price":21.95,"currency_code":"GBP","in_stock":true},{"title":"Inc 4 x AA \u0026 4 x AAA Lithium Batteries","offer_id":44553842819114,"sku":"XTA-CH-03258","price":39.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/8098\/7434\/files\/XTAR_MX4_1__50566.1765368404.1280.1280.jpg?v=1778507620","url":"https:\/\/www.batterystation.co.uk\/products\/xtar-mx4-mini-mixer-1-5v-3-7v-lithium-aa-aaa-nimh-charger","provider":"BatteryStation.co.uk","version":"1.0","type":"link"}
