Having too many redundant backup devices can actually reduce the up time of the system. This was seen at the Superbowl in New Orleans. http://www.espn.com/nfl/story/_/id/9082144/relay-device-malfunction-caused-super-bowl-xlvii-power-outage-according-expert It is also very dangerous to assume that your backups are adequate and that you don't have to watch the log files. If somebody had been reading the logs, they would have seen the message that essentially said: "I have reported two power surges and you haven't told me what to do. Although these are not individually dangerous, one more power surge before somebody talks to me and I shut down the entire stadium." | Having too many redundant backup devices can actually reduce the up time of the system.

+ | What if the backup batteries are actual removable batteries? [[Special:Contributions/141.101.76.226|141.101.76.226]] 05:03, 6 August 2017 (UTC) | ||
An optimist states that the water glass is half full, while a pessimist states that the water glass is half empty. What an engineer really does is find out where the water faucet is so that he can refill the glass as needed. (The original joke says that the engineer states that the glass is twice as large as needed. This is ridiculous unless he knows how much water is needed and how much is available at the faucet. The size of this glass is irrelevant unless it is too large to be handled easily or too small to transport water at the required rate.) | An optimist states that the water glass is half full, while a pessimist states that the water glass is half empty.

Assuming he charges the batteries in series (i.e. the second backup charges the first backup which charges the phone, etc.) I wonder how many batteries he'd be able to go through, before the charging/discharging inefficiency (heat generation etc.) meant none of the original power would get to the phone? | Assuming he charges the batteries in series (i.e. the second backup charges the first backup which charges the phone, etc.) I wonder how many batteries he'd be able to go through, before the charging/discharging inefficiency (heat generation etc.) meant none of the original power would get to the phone? | ||
β | Also I can relate to this comic, when traveling I may bring 2-3 batteries, even though in practice I rarely need more than one ππ. 18:58, 4 August 2017 (UTC) | + | Also I can relate to this comic, when traveling I may bring 2-3 batteries, even though in practice I rarely need more than one ππ. 18:58, 4 August 2017 (UTC) {{unsigned ip|108.162.246.11}} |
β | :EDIT: Replying to below comments, I have a power bank that allows simultaneous discharging and charging. Also I really meant to say it as them being charged/drained in sequence, rather than all simultaneously. | + | :EDIT: Replying to below comments, I have a power bank that allows simultaneous discharging and charging.

I think the 20% full doesn't mean the energy capacity of the backpack, but the actual contents of the backpack. If it is less than 20% (charged) backup battery, he panics.
