For those sport nuts or others who just can’t get away from their TV, why not try the Casio EV-570 Handheld Portable?
The 2.5 inch screen ( of course it’s small! if not it won’t be called handheld!) will lasts around 2 hours with 4 AAAA batteries. If you have a power source around, it can also be plugged on.

This lightweight tv has good clarity and reception ( UHF & VHF). Just don’t expect to see the score of your basketball game because it’s so tiny you’ll break your eyeball.

Oh! In case you decided to buy it, just remember to invest in rechargable batteries (and maybe save some money for a pair of eyeglasses) too ..
