Two Kastar battery-and-charger bundles for Sony cameras sit at different price points: the Kastar Battery LTD2 USB Charger for NP-FZ100 & Sony Alpha A7 IV Α7iv Camera is built around the NP-FZ100 cell used in the Alpha A7 IV, while the Kastar Battery Slim USB Charger for Sony NP-BG1 NP-FG1 Sony Cyber-shot DSC-W120 targets NP-BG1 and NP-FG1 batteries found in Cyber-shot models like the DSC-W120. The real decision isn't just cost - it's which battery family your camera takes.
Quick Verdict
The LTD2 bundle is the lower-priced kit at $9.99, and it packs more capacity while including a charger that can handle two batteries at once. The Slim USB bundle costs more at $18.19, but it's the only one here that fits NP-BG1 and NP-FG1 cameras. Match the battery model first, then weigh capacity and price.
At a Glance
| Product | Listed Price | Capacity | Charger | Price Bar |
|---|---|---|---|---|
| Kastar Battery LTD2 USB Charger for NP-FZ100 & Sony Alpha A7 IV Α7iv Camera | USD 9.99 | 2280mAh | Included, 2-slot USB | |
| Kastar Battery Slim USB Charger for Sony NP-BG1 NP-FG1 Sony Cyber-shot DSC-W120 | USD 18.19 | 1600mAh | Included, slim USB |
Where Each Bundle Wins
The LTD2 kit takes the lead on capacity. Its USB charger accepts 5V 2-3A input, outputs 8.4V, and can charge two batteries at the same time with a changeable plate for different battery types. It is also compatible with Sony charger models BC-QZ1 and NPA-MQZ1K, which adds flexibility for Alpha-series owners.
The Slim USB kit is the match for the NP-BG1/NP-FG1 family. Its charger is ultra-slim with a Micro USB input and an LED that shows red while charging and green for standby or full charge. A Micro USB cable is included, and the battery itself is a lower-capacity Li-Ion cell at 3.7V. For Cyber-shot DSC-W120 users, this is the compatible bundle.
Both are Kastar Li-Ion batteries with integrated microchips to prevent overcharge and over-discharge, and both include the charger in the box. Each is a bundle listing with a California Prop 65 warning.
Product Notes
Kastar Battery LTD2 USB Charger for NP-FZ100 & Sony Alpha A7 IV Α7iv Camera
This bundle pairs a 2280mAh NP-FZ100 replacement battery with a USB charger rated at 5V 2-3A input and 8.4V output. It can charge two batteries at once, and the plate can be swapped to fit different battery shapes. It is also compatible with Sony BC-QZ1 and NPA-MQZ1K chargers. The limitation is its focus on NP-FZ100 cameras - if your Sony uses NP-BG1 or NP-FG1 cells, this kit won't fit. For Alpha A7 IV shooters, the capacity and dual-bay charging make it a strong choice.
Kastar Battery Slim USB Charger for Sony NP-BG1 NP-FG1 Sony Cyber-shot DSC-W120
This bundle fits NP-BG1 and NP-FG1 batteries. The included cell offers 1600mAh at 3.7V, and the charger is ultra-slim with a Micro USB input and an LED that changes from red (charging) to green (standby or full). A Micro USB cable comes in the box. The trade-off is the lower capacity relative to the NP-FZ100 kit, and the charger's 4.2V output is suited to the smaller battery format. For Cyber-shot owners, it's the purpose-built option.
Final Choice by Use Case
- Sony Alpha A7 IV shooters: Go with the Kastar Battery LTD2 USB Charger for NP-FZ100 & Sony Alpha A7 IV Α7iv Camera - it matches the NP-FZ100 battery model, carries more capacity, and includes a two-slot charger.
- Sony Cyber-shot DSC-W120 (or NP-BG1/NP-FG1) shooters: Choose the Kastar Battery Slim USB Charger for Sony NP-BG1 NP-FG1 Sony Cyber-shot DSC-W120 - it's the only bundle here built for those battery models.
- If capacity matters most: The LTD2 kit outpaces the Slim USB kit on capacity.
