So in regards to carrying mass batteries is there a group style charger to keep them charged. ...Any one outlet chargers for mass batteries around now?
There are no 808-style gang chargers that I've found. There are 5- and 10-gang 510 chargers but they generally provide only 100-150mAh charging current and in some cases that seems to be shared so charging multiple batteries takes on the order of 4 to 6 hours (I had one group that took nearly 8 hours to fully charge).
The best solution I've found so far is a Rosewill RHB-330 7-port USB hub from Newegg that has five of the ports mounted on top and includes a 2.1 amp wall wart power supply with roughly six-foot cord.
Only three chargers are pictured here but since then I've filled all five of the top ports with USB chargers and use the other two on the side for other chargers (PCC, eGo, etc.). I keep the whole thing Velcro'd near the back of my work bench. It's about $20 for the hub plus whatever you put into chargers (about $7.00 each). While it seems a little spendy it's a viable solution that works very well.
There are some generic USB hubs on Amazon with 10 top-mounted ports for under $10 that might work, but reports on the power supply output and power pass-through to the ports were iffy enough that I didn't go for it.
Hope this helps!
