Kastar NP-FW50 Kit

This kit supplies two lithium-ion batteries and a quadruple USB charger for Sony mirrorless and compact cameras that use the NP-FW50 cell. Each battery delivers 7.2 volts and 1650 milliampere-hours, giving 11.8 watt-hours of capacity. The charger accepts Micro-USB or USB-C input and can charge up to four batteries simultaneously. It suits photographers who need reliable spares for long shooting days.

Replacing single-bay chargers

A single-slot charger forces you to cycle batteries one at a time, which slows turnover on multi-day trips. The quad charger handles four cells at once, with intelligent status display for each bay. Output drops from 800 milliamps per slot for one or two batteries to 500 milliamps when three or four are loaded. The jump is worth it when you regularly carry three or more spares and want them ready overnight.

Capacity and headroom

Two 1650 mAh packs cover a full day of stills or mixed stills and video for most compatible bodies. Video-heavy sessions with continuous recording will drain a single battery faster, so the second pack provides a practical buffer. The charger's 15 watt input limits total throughput when all four bays are occupied, extending the full-cycle time. Users who need more than two full cycles per day should plan for additional batteries.
