The short answer on noco genius 5 vs noco genius 10: the listings behind this comparison are not the two chargers. One side is a NOCO jump starter and the other is a NOCO eyelet accessory for GENIUS chargers. Choose the jump starter if the job is starting a dead vehicle; choose the eyelet accessory if the job is wiring a permanent plug-in point for a GENIUS charger.

What the listings actually are
The side tagged noco genius 5 is the NOCO GC002 X-Connect M6 eyelet terminal accessory, not the GENIUS5 battery charger. The side tagged noco genius 10 is the NOCO Boost GBX155 jump starter, not the GENIUS10 battery charger. The comparison below uses what these two listings state; it cannot compare the actual GENIUS5 and GENIUS10 chargers because neither listing is one.
Power and protection
The GBX155 states 4250A peak output on 12V, with spark-proof and reverse polarity protection, a 6750mAh battery and 60W USB-C power delivery. The GC002 states a 20A micro blade fuse guarding against shorts, copper-plated eyelets and a connector that seals out dirt and water. These are different jobs, so the protection figures do not compete.
Use and compatibility
The GBX155 is made for jump starting gas engines up to 10.0L and diesel up to 8.0L, with up to 18 jump starts per charge and an integrated LED flashlight. The GC002 mounts M6 eyelets on battery terminals once, then lets a GENIUS charger plug in on an 18.5-inch cable; it states compatibility with GENIUS1, GENIUS2, GENIUS2X2, GENIUS2X4, GENIUS5 and GENIUS10.
Warranty
Both listings state a 1-year warranty: 1 year on the GBX155 and 1-year limited on the GC002.
What the listings leave unclear
Neither listing is the charger its side is named for, so no charger-to-charger comparison can be drawn from them. The GBX155 listing states no engine figures beyond the 10.0L gas and 8.0L diesel limits. The GC002 listing states a sealed connector without a stated weather code.
