Product notes
Kastar Canon NB-4L Charger + Battery for PowerShot SD600/SD630
Choose this Kastar kit when your camera takes NB-4L or NB-4LH batteries. It pairs a wall charger with a lithium-ion battery, and the charger outputs 4.2V/600mA while showing red for charging and green for standby or full charge. The charger also folds flat for storage, making it easy to tuck into a bag. The limitation is that it is the higher-priced kit in this head-to-head, so Canon PowerShot owners pay more for the specific fit.
Kastar Nikon EN-EL3e Charger + Battery for D90
This Kastar bundle fits the Nikon D90's EN-EL3e battery slot. The charger outputs 8.4V/600mA and folds flat for storage, and the included battery is lithium-ion with overcharge and over-discharge protection. It is the lower-priced kit here, giving Nikon D90 shooters a direct match without the higher cost of the Canon-side listing. The limitation is that it only suits Nikon equipment of this type, so Canon PowerShot owners should pick the other kit.
Final choice by use case
For a Canon PowerShot SD600 or SD630 owner, the Kastar Canon NB-4L charger bundle is the right fit, even though it is the higher-priced listing. For a Nikon D90 owner, the Kastar EN-EL3e bundle is the clear match.
