Panasonic Energy, a French branch of the Japanese company that makes eneloop rechargeable batteries, announced on September 30 the BQ-CCE5, a fast charger that uses USB-C technology. This device allows users to recharge AA or AAA batteries using a USB-C cable and a power adapter from their smartphone, eliminating the need to plug the charger directly into a wall outlet. The Japanese website Kaden Watch reported on this announcement, noting that the release is specific to Japan, with a planned launch date of late October 2026. The eneloop batteries are NiMH (nickel-metal hydride) batteries introduced by Sanyo in 2005 and later acquired by Panasonic. They are known for their ability to retain charge for months when stored, unlike older rechargeable batteries that would lose charge over time. In Japan, the BQ-CCE5 charger costs 2,980 yen, or about 17 euros, when purchased directly. Panasonic also sells it in kits with four eneloop Standard batteries in AA format (reference K-KJE5MCD40) or AAA format (K-KJE5MCD04), priced at 4,480 yen each, or around 25 euros. Retailers are free to set their own prices, as Panasonic does not recommend specific pricing. Neither the USB-C cable nor the power adapter is included in the charger, even in the kits. The charger can handle one to four AA or AAA batteries, which can be mixed as desired. Panasonic claims it takes about 1 hour and 30 minutes to recharge two AA eneloop Standard batteries using a charger that provides at least 2 amps. At 5 volts, this corresponds to 10 watts, a power level easily provided by most smartphone fast chargers. Each slot in the charger independently analyzes the battery and adjusts the charge based on its condition. A three-color LED indicates the charge level and alerts users to batteries that are too worn and need replacing. The charger also detects batteries damaged by deep discharge and first recharges them at a low current. It stops charging a battery once it is fully charged and allows partial recharges. Most importantly, it prevents accidental charging of alkaline batteries. The charger is compact, measuring 66 × 28 × 89 millimeters and weighing about 80 grams, roughly the size of a slightly thick deck of cards. According to the Japanese product sheet, it is compatible with two battery families: eneloop and Evolta, a rechargeable line no longer in production. Outside Japan, Panasonic already sells eneloop chargers that use USB. For example, the BQ-CC87 uses 5 volts but requires a USB-A to micro-USB cable, a connector most smartphones have phased out. Panasonic also specifies that only eneloop and eneloop Pro batteries should be charged. As a result, there is hope that the USB-C charger will soon be available in Europe.
