Hi, first of all, thank you very much for updating to 0.15 XD
Now Beacon's amount of power is enough to use it three times.
Yes, i think beacons are balanced and the recharge rate is ok.
If you want to hear my opinion about the personal teleporter: It always bothered me, that the personal teleporter has a fixed recharge rate. Sometimes you forget a few items, teleport multiple times in a short amount of time and suddenly you are without teleport and must wait forever. The problem is, that the teleporter does not charge more quickly with more fusion reactors, nor uses battery power. This is different from all other equipment. Why does my teleporter have no energy when I have full batteries? Therefore I have already used in 0.14 the following settings for myself:
type = "electric",
buffer_capacity = "50MJ",
input_flow_limit = "1GW",
output_flow_limit = "0W",
usage_priority = "secondary-input"
The Teleporter now mainly uses the battery power (the battery indicator can also be used to estimate how many jumps you still have). In addition, the player has the option to increase his jump portal range or the number of his beacon jumps at the cost of space in the equipment grid for batteries. This gives the player more freedom and the teleporter felt less arbitrary to me. XD
..., but you can equip several Teleporters.
He, i have never thought about eqipping multiple teleporters O0
Maybe you find the jump portal too strong after these changes, but you could compensate that by increasing the jump portal energy cost.
I will use these settings anyways, but you can try them out yourself and decide if you like it or not.
