Each bay determines the appropriate charging method automatically, applying voltage and current profiles suited to lithium-based cells and NiMH formats. This configuration enables independent charging behaviour, allowing multiple battery types to be processed simultaneously without user adjustment. The design supports all three major rechargeable categories—1.5 V lithium AA\/AAA, 1.2 V NiMH AA\/AAA, and 3.6\/3.7 V lithium-ion—making it the first charger in its class capable of charging all three within one system.\u003c\/p\u003e\n\u003cp\u003eIts USB-C input provides stable low-voltage power, while internal control logic manages charge progression and termination. LED indicators present slot-by-slot status, and built-in safeguards help regulate operation during routine use. The mechanical layout supports common cylindrical sizes and offers activation support for cells that have fallen below typical operating voltage. Unlike capacity-limited chargers, the MX4 imposes no maximum mAh rating; it determines charge completion by monitoring voltage behaviour rather than battery capacity, enabling compatibility with high-capacity cells.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour independent charging bays operating with multi-chemistry support.\u003c\/li\u003e\n\u003cli\u003eSupports all three major rechargeable battery types: 1.5 V lithium AA\/AAA, 1.2 V NiMH AA\/AAA and 3.6\/3.7 V lithium-ion (e.g., 18650 series).\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFirst charger of its kind capable of charging all three types simultaneously in one unit.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNo maximum battery capacity limit — charging completion is voltage-based, not dependent on mAh rating.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eAutomated identification of Li-ion, LiFePO₄, 1.5 V lithium rechargeable, and NiMH cells.\u003c\/li\u003e\n\u003cli\u003eUSB-C power input for stable charging performance.\u003c\/li\u003e\n\u003cli\u003ePer-slot LED indicators for real-time charging feedback.\u003c\/li\u003e\n\u003cli\u003eCompatible with various cylindrical sizes including 10440, 14500, 16340, 18650, 20700 and unprotected 21700.\u003c\/li\u003e\n\u003cli\u003eSuitable for AA\/AAA NiMH and 1.5 V lithium rechargeable formats.\u003c\/li\u003e\n\u003cli\u003eIntegrated safety functions including over-charge control and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003eActivation capability for certain heavily discharged batteries.\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\u003eCharging slots:\u003c\/strong\u003e 4 independent bays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported chemistries:\u003c\/strong\u003e Li-ion 3.6\/3.7 V, LiFePO₄ 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\u003eMaximum charging current:\u003c\/strong\u003e 1 A on two slots or 0.5 A on four slots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported Li-ion formats:\u003c\/strong\u003e 10440, 14500, 16340, 18350, 18500, 18650, 18700, 20700, unprotected 21700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported NiMH formats:\u003c\/strong\u003e AAA, AA, A, SC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported 1.5 V lithium formats:\u003c\/strong\u003e AA, AAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery length range:\u003c\/strong\u003e Approximately 34–70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge indication:\u003c\/strong\u003e LED status per slot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection features:\u003c\/strong\u003e Over-charge, short-circuit, low-voltage activation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e21700 compatibility:\u003c\/strong\u003e Unprotected cells only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Xtar","offers":[{"title":"None","offer_id":56289120223610,"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":56289135919482,"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":56289135952250,"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":56289135985018,"sku":"XTA-CH-03255","price":44.95,"currency_code":"GBP","in_stock":true},{"title":"Inc 4 x AA Lithium Batteries","offer_id":56289136017786,"sku":"XTA-CH-03256","price":26.95,"currency_code":"GBP","in_stock":true},{"title":"Inc 4 x AAA Lithium Batteries","offer_id":56289136050554,"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":56289136083322,"sku":"XTA-CH-03258","price":39.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/8622\/6060\/files\/XTARMX4_1_eaacf981-b9d8-4a59-9cf6-b350cfc52fbf.jpg?v=1765377478"},{"product_id":"xtar-mx8-8-slot-1-5v-3-7v-lithium-aa-aaa-nimh-smart-charger","title":"Xtar MX8 8-Slot 1.5V, 3.7V Lithium \u0026 AA\/AAA NiMH Smart Charger","description":"\u003cp\u003eThe Xtar MX8 is an eight-bay charging platform developed for applications requiring the ability to manage several battery chemistries at the same time.
