Our take: The VB-Power standard wall charger for large-type battery packs is an economical way of charging your large-type battery (battery w/ standard Tamiya plug). While we recommend the use of a smart charger to ensure that your battery does not get overcharged in the event of user error/overlook, the standard wall charger works great for those looking for a cheap battery alternative.
Compatible with: 8.4v and 9.6v large-type batteries
Output: 300mah current
NOTE: Standard wall chargers, if not watched/timed carefully during charging, can overcharge and cause damage to your battery. To make sure you do not overcharge your battery, please follow the charging time formula provided below.
Proper charge time formula for your battery (quoted from our Player Resource Center):
The general rule for charging a battery is to charge the battery for X hours, where X is the number you get after dividing the MAH of the battery by the MAH of the charger (found on the charger's sticker).
For example: You are charging an 8.4V standard 3000 MAH large battery with this charger, which outputs 300mah (as listed above).
CHARGE THIS PARTICULAR COMBO for: 3000 divided by 300 = 10 hours
