Claim:
1. An electrical charging system, comprising: a first standby battery product having a first battery casing with a first electricity storage unit housed inside the first battery casing, the first battery casing further including a first power input interface on the first battery casing, a first elastic conductive pin and a first conductive contact, the first elastic conductive pin and first conductive contact being electrically connected to the first electricity storage unit and the first power input interface, the first battery casing further including a plurality of first couplers; a second standby battery product having a second battery casing with a second electricity storage unit housed inside the second battery casing, the second battery casing further including a second power input interface on the second battery casing, a second elastic conductive pin and a second conductive contact, the second conductive elastic pin and second conductive contact being electrically connected to the second electricity storage unit and the second power input interface, the second battery casing further including a plurality of second couplers; wherein the second elastic conductive pin is aligned with, and contacts, the first elastic conductive contact, and the first couplers engage the second couplers, when the second battery casing is placed on top of the first battery casing; and wherein the first and second standby battery products are identical to each other; wherein the first couplers are first magnets, and the second couplers are second magnets oriented at a different polarity from the first magnets; and wherein a first charging path is defined by the first power input interface of the first battery casing and the first electricity storage unit, and a second charging path is defined by the first power input interface of the first battery casing, the first conductive contact of the first battery casing, the second elastic conductive pin of the second battery casing, and the second electricity storage unit of the battery product.
